Public bug reported:

Here is what I sent to Grok, and the reply. I tried many of these, as
you will see:

I recently updated Ubuntu from 25.04 to 25.10. After doing this upgrade,
one of my icons is missing. The "software updater", which is an A with a
circle around it, is no longer there. Where did it go?


1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description:	Ubuntu Questing Quokka (development branch)
Release:	25.10


2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
??

3) What you expected to happen
Wanted to see the updates come in on the software updater.

4) What happened instead
It is not working properly.


The Software Updater (officially called "update-manager" in Ubuntu) is a standard application included by default in Ubuntu Desktop editions, including 25.10. It should appear in your applications overview (accessed via the Super key or Activities button) under the "Administration" category, with its icon being a blue circle around a white "A" (representing "updates available"). If it's missing after your upgrade from 25.04, this is likely due to one of a few common issues: an incomplete upgrade process, a missing or broken package, icon theme glitches, or a change in how the desktop environment handles pinned or visible apps.
Quick Checks and Fixes

    Search for It in the Applications Menu:
        Press the Super key (Windows key) and type "software updater" or "update manager".
        If it appears in the search results but isn't showing in the grid or dock, it exists but may not be pinned or visible by default. Right-click it and select "Add to Favorites" to pin it to your dock.
    Launch It via Terminal to Verify:
        Open a terminal (Ctrl+Alt+T) and run:
        text

    update-manager

    If it launches successfully, the app is installed but the
icon/shortcut is the issue. If it doesn't launch (e.g., "command not
found"), proceed to reinstall it.

Reinstall the Software Updater Package:

    Upgrades can sometimes fail to carry over certain packages cleanly. Run these commands in the terminal:
    text

    sudo apt update
    sudo apt install --reinstall update-manager

    This will reinstall the app without affecting your system. After it
completes, search for it again in the applications menu or relaunch via
terminal. Log out and back in (or reboot) if the icon still doesn't
appear.

Fix Icon or Desktop Integration Issues:

    Reset GNOME Extensions: Ubuntu 25.10 uses GNOME 49 (with Wayland as default), and extensions can glitch during upgrades, causing icons to vanish from the dock or overview. Install the Extensions app if needed (sudo apt install gnome-shell-extension-manager), then:
        Open Extensions > Go to the "Installed" tab.
        Disable all extensions, log out/in, then re-enable them one by one to identify any culprits.
        Alternatively, reset all extensions via terminal:
        text

    gnome-extensions reset

    Then log out and back in.

Update Icon Cache: If the icon specifically is broken:
text

    sudo gtk-update-icon-cache /usr/share/icons/hicolor

    Restart your session afterward.
    Check for Conflicting Themes: Go to Settings > Appearance and switch to the default "Yaru" theme temporarily to see if a custom theme is hiding the icon.

Ensure No Upgrade Artifacts:

    Run a full system upgrade to catch any missed packages:
    text

        sudo apt update && sudo apt full-upgrade

        If you have third-party PPAs or snaps from 25.04, they might
conflict—disable them temporarily in Software & Updates (which you can
launch via software-properties-gtk in terminal).

If It Still Doesn't Work

    Check if you're on the standard Ubuntu Desktop (GNOME). Run echo $XDG_CURRENT_DESKTOP in terminal—it should output "ubuntu:GNOME". If it's something else (e.g., due to a partial install), reinstall the full desktop:
    text

    sudo apt install ubuntu-desktop

    Search for bugs: Visit the Ubuntu Discourse forums or Launchpad and look for "update-manager icon missing 25.10". Upgrades from interim releases like 25.04 to 25.10 can occasionally skip UI elements.
    As a workaround, you can always update via terminal (sudo apt update && sudo apt upgrade) or use the "Software" app (GNOME Software) for graphical updates, which handles most of the same tasks.

This should restore it—upgrades are generally smooth, but icon visibility is a frequent hiccup in GNOME-based releases. If you provide more details (e.g., error messages from terminal), I can refine the advice.
1.2s
This used to come up with a list of software to install, and you could check off which ones you wanted. It would tell you how much space it took, and the versions. I do not see this now.

It sounds like you're describing the functionality of the Software Updater (update-manager) in Ubuntu, which typically shows a list of available updates for installed software, including package names, versions, and the size of the updates, allowing you to selectively install them. If this interface is no longer appearing after your upgrade to Ubuntu 25.10 and the icon is missing, it’s likely that the update-manager package is either not installed, corrupted, or misconfigured, or the desktop environment is not displaying it correctly. Let’s troubleshoot and restore this functionality.
Steps to Resolve the Issue

    Verify Software Updater is Installed:
        Open a terminal (Ctrl+Alt+T) and run:
        text

    update-manager

    If it launches and shows the familiar interface (a list of updates
with checkboxes, version details, and sizes), the app is installed but
not appearing in your applications menu or dock. If it fails with an
error (e.g., "command not found"), proceed to reinstall.

Reinstall Software Updater:

    Run the following commands to ensure the package is properly installed:
    text

    sudo apt update
    sudo apt install --reinstall update-manager

    After reinstalling, try launching it again with update-manager. If
it opens and shows the update list with checkboxes, versions, and sizes,
the core issue is resolved. Now, we need to fix the icon visibility.

Check for the Icon in the Applications Menu:

    Press the Super key (Windows key) and search for "Software Updater" or "Update Manager".
    If it appears in the search but not in the applications grid or dock, right-click it and select "Add to Favorites" to pin it to the dock, or drag it to your desired location.
    If it doesn’t appear in the search, the desktop file may be missing or corrupted. Create or restore it:
    text

sudo nano /usr/share/applications/update-manager.desktop

Ensure it contains (or create it with) the following:
text

[Desktop Entry]
Name=Software Updater
Comment=Show and install available updates
Exec=update-manager
Icon=system-software-update
Terminal=false
Type=Application
Categories=System;Settings;

Save (Ctrl+O, Enter, Ctrl+X) and run:
text

    sudo chmod +x /usr/share/applications/update-manager.desktop
    sudo update-desktop-database

    Log out and back in, then search for it again.

Check for GNOME Software Interference:

    Ubuntu 25.10 uses GNOME Software (gnome-software) alongside Software Updater, and sometimes the system defaults to GNOME Software for updates, which has a different interface (less detailed, no checkboxes for individual packages).
    To confirm you’re using Software Updater and not GNOME Software:
        Run update-manager in terminal to ensure you get the detailed interface with package lists, versions, and sizes.
        If GNOME Software is opening instead when you click updates, go to Settings > Software & Updates > Updates tab and ensure "Check for updates" is set to a regular interval (e.g., daily). This ensures update-manager is triggered for updates.
    If you prefer GNOME Software but want the detailed view, you may need to rely on update-manager explicitly or use terminal commands (apt list --upgradable to see available updates with versions).

Fix Icon or Desktop Environment Issues:

    Icon Cache Issue: If the icon (blue circle with a white "A") is missing or broken:
    text

sudo gtk-update-icon-cache /usr/share/icons/hicolor

Log out and back in.
GNOME Shell Glitch: Ubuntu 25.10 uses GNOME 49, and upgrades can disrupt shell extensions or icon rendering. Reset GNOME Shell settings:
text

    dconf reset -f /org/gnome/shell/

    Then reboot. This resets the application grid and dock to defaults, which may restore the icon.
    Theme Conflict: Go to Settings > Appearance and switch to the default Yaru theme to rule out a custom theme hiding the icon.

Alternative: Check Updates via Terminal:

    If the GUI is still not working, you can view the same information (package names, versions, sizes) in the terminal:
    text

sudo apt update
apt list --upgradable

This lists all available updates with their current and new versions. To selectively install updates, use:
text

    sudo apt install <package-name>

    For example, sudo apt install firefox to update only Firefox. This
replicates the checkbox functionality of Software Updater.

Verify Upgrade Integrity:

    Upgrades from 25.04 to 25.10 can sometimes leave packages in an inconsistent state. Run:
    text

        sudo apt update && sudo apt full-upgrade
        sudo apt autoremove
        sudo apt autoclean

        This ensures all dependencies are resolved and stray packages are cleaned up.
    Check for Known Bugs:
        Search Ubuntu’s Launchpad (https://bugs.launchpad.net/ubuntu) or the Ubuntu Discourse forums for "update-manager missing 25.10" or "software updater no icon". This can reveal if others are experiencing the same issue post-upgrade.
        If you suspect a bug, consider reporting it with ubuntu-bug update-manager in the terminal to help the community diagnose it.

Additional Notes

    Snap vs. APT: Ubuntu 25.10 uses a mix of APT (deb packages) and Snap for software. Software Updater handles APT updates, while Snap updates are managed by snap refresh or GNOME Software. To see Snap updates:
    text

snap refresh --list

If you’re expecting Snap package details in the updater, you’ll need to use GNOME Software or the terminal, as update-manager doesn’t list Snaps.
Fallback to GNOME Software: If you can’t restore Software Updater, GNOME Software (gnome-software) can handle updates but with less granularity (no checkboxes or detailed size/version info). Launch it via:
text

    gnome-software

    Go to the Updates tab to apply updates.

If It’s Still Missing

If none of these steps restore the Software Updater with its detailed
interface:

    Confirm your desktop environment with echo $XDG_CURRENT_DESKTOP. It should say ubuntu:GNOME. If it’s different, you may have a partial desktop install. Reinstall the full Ubuntu desktop:
    text

    sudo apt install ubuntu-desktop

    Provide more details (e.g., any errors when running update-manager,
whether GNOME Software is showing updates, or if you use a custom
desktop setup), and I can tailor further steps.

This should get you back to the familiar Software Updater interface with the list of updates, checkboxes, versions, and sizes. Let me know how it goes or if you hit specific errors!

Unsatisfied dependencies:
 update-manager : Depends: gir1.2-snapd-2 but it is not going to be installed
                  Depends: ubuntu-release-upgrader-gtk but it is not going to be installed
                  Depends: update-notifier
Error: Unable to satisfy dependencies. Reached two conflicting decisions:
   1. ubuntu-release-upgrader-gtk:amd64 is selected for install because:
      1. update-manager:amd64=1:25.04.5 is selected for install
      2. update-manager:amd64 Depends ubuntu-release-upgrader-gtk
   2. ubuntu-release-upgrader-gtk:amd64 Depends gir1.2-webkit2-4.1
      but none of the choices are installable:
      - gir1.2-webkit2-4.1:amd64 is available in versions 2.48.3-1ubuntu2, 2.48.6-1ubuntu1
        but none of the choices are installable:
        - gir1.2-webkit2-4.1:amd64=2.48.3-1ubuntu2 Depends libwebkit2gtk-4.1-0 (= 2.48.3-1ubuntu2)
          but none of the choices are installable:
          - libwebkit2gtk-4.1-0:amd64=2.48.3-1ubuntu2 is not selected for install
        - gir1.2-webkit2-4.1:amd64=2.48.6-1ubuntu1 is not selected for install

The error you're encountering indicates that update-manager cannot be installed or reinstalled due to unmet dependencies, specifically gir1.2-snapd-2, ubuntu-release-upgrader-gtk, and update-notifier. The root of the issue seems to be a dependency conflict with ubuntu-release-upgrader-gtk, which requires gir1.2-webkit2-4.1, but the available versions of gir1.2-webkit2-4.1 (2.48.3-1ubuntu2 or 2.48.6-1ubuntu1) have their own dependency issues, particularly with libwebkit2gtk-4.1-0. This is a common issue after an Ubuntu upgrade (e.g., from 25.04 to 25.10), as package repositories or dependency chains can become misaligned. Let’s resolve this step-by-step to restore the Software Updater and its icon.
Steps to Fix Unmet Dependencies

    Update Package Lists:
        Ensure your package lists are up-to-date to rule out stale repository data:
        text

sudo apt update

If you get errors about missing or unreachable repositories, check your sources in /etc/apt/sources.list and /etc/apt/sources.list.d/. Ensure they point to Ubuntu 25.10 (Oracular Oriole) repositories. For example:
text

    deb http://archive.ubuntu.com/ubuntu/ oracular main restricted universe multiverse
    deb http://archive.ubuntu.com/ubuntu/ oracular-updates main restricted universe multiverse
    deb http://security.ubuntu.com/ubuntu/ oracular-security main restricted universe multiverse

    Edit with sudo nano /etc/apt/sources.list if needed, then run sudo
apt update again.

Fix Broken Dependencies:

    Run the following to attempt automatic dependency resolution:
    text

    sudo apt install -f

    This command tries to fix broken or missing dependencies by
installing or removing conflicting packages. If it reports specific
conflicts, note them for the next steps.

Install Missing Dependencies Explicitly:

    The error mentions gir1.2-snapd-2, ubuntu-release-upgrader-gtk, and update-notifier. Try installing them individually to identify the root issue:
    text

sudo apt install gir1.2-snapd-2
sudo apt install ubuntu-release-upgrader-gtk
sudo apt install update-notifier

If any fail, the error output will point to the specific conflict. For example, ubuntu-release-upgrader-gtk depends on gir1.2-webkit2-4.1, which depends on libwebkit2gtk-4.1-0. Try installing the specific version mentioned:
text

sudo apt install libwebkit2gtk-4.1-0=2.48.3-1ubuntu2
sudo apt install gir1.2-webkit2-4.1=2.48.3-1ubuntu2

If version 2.48.3-1ubuntu2 fails, try the alternative:
text

    sudo apt install libwebkit2gtk-4.1-0=2.48.6-1ubuntu1
    sudo apt install gir1.2-webkit2-4.1=2.48.6-1ubuntu1

Clean Up Package Cache and Remove Conflicts:

    Clear out any corrupted or partial packages:
    text

sudo apt clean
sudo apt autoclean
sudo apt autoremove

If a specific package is causing conflicts (e.g., libwebkit2gtk-4.1-0), try removing it temporarily (if it’s not critical) and reinstalling:
text

    sudo apt remove libwebkit2gtk-4.1-0
    sudo apt install update-manager

Check for Held or Locked Packages:

    Sometimes, packages are held back, causing dependency issues. Check for held packages:
    text

dpkg --get-selections | grep hold

If any packages are listed, unhold them:
text

sudo apt-mark unhold <package-name>

Then retry installing update-manager:
text

    sudo apt install update-manager

Force Installation of Compatible Versions:

    If the specific versions of libwebkit2gtk-4.1-0 or gir1.2-webkit2-4.1 are unavailable or conflicting, you can try forcing a compatible version. First, check available versions:
    text

apt-cache policy libwebkit2gtk-4.1-0
apt-cache policy gir1.2-webkit2-4.1

If a compatible version exists in the repository, install it explicitly:
text

    sudo apt install libwebkit2gtk-4.1-0=<version>
gir1.2-webkit2-4.1=<version>

    Replace <version> with a version from the apt-cache policy output
that matches your system’s architecture (amd64).

Reinstall the Full Ubuntu Desktop:

    If the dependencies are too tangled, reinstalling the Ubuntu desktop environment can resolve missing or broken system components:
    text

    sudo apt install ubuntu-desktop

    This pulls in update-manager, update-notifier, and their
dependencies, ensuring a consistent setup for Ubuntu 25.10’s GNOME 49
environment.

Check for Third-Party Repositories or PPAs:

    Third-party PPAs from Ubuntu 25.04 may be causing conflicts in 25.10. List your PPAs:
    text

ls /etc/apt/sources.list.d/

If any PPAs are present, disable them temporarily:
text

    sudo mv /etc/apt/sources.list.d/<ppa-file> /etc/apt/sources.list.d/<ppa-file>.bak
    sudo apt update

    Then retry installing update-manager.

Verify Snap Integration:

    The dependency gir1.2-snapd-2 relates to Snap package integration. Ensure the Snap daemon is installed and running:
    text

sudo apt install snapd
sudo systemctl enable --now snapd

Then retry:
text

    sudo apt install gir1.2-snapd-2

Restore Software Updater Icon and Functionality:

    Once the dependencies are resolved and update-manager installs successfully, ensure the desktop file is present:
    text

sudo nano /usr/share/applications/update-manager.desktop

Verify or add:
text

[Desktop Entry]
Name=Software Updater
Comment=Show and install available updates
Exec=update-manager
Icon=system-software-update
Terminal=false
Type=Application
Categories=System;Settings;

Save, then update the desktop database:
text

sudo chmod +x /usr/share/applications/update-manager.desktop
sudo update-desktop-database

Update the icon cache:
text

    sudo gtk-update-icon-cache /usr/share/icons/hicolor

    Log out and back in, then search for "Software Updater" in the
applications menu. Launch it to confirm it shows the list of updates
with checkboxes, versions, and sizes.

Fallback: Use Alternative Update Tools:

    If update-manager still won’t install, you can manage updates via the terminal or GNOME Software:
        Terminal:
        text

sudo apt update
apt list --upgradable
sudo apt upgrade

This lists packages with versions and sizes, similar to Software Updater, though without a GUI checkbox interface.
GNOME Software:
text

gnome-software

Go to the Updates tab. It’s less detailed but can apply updates.
Synaptic Package Manager (if you prefer a GUI with detailed control):
text

            sudo apt install synaptic
            synaptic

            Synaptic allows you to see and select individual package
updates with version and size details.

If Problems Persist

    Check Logs for Specific Errors:
        Review APT logs for more clues:
        text

    cat /var/log/apt/term.log
    cat /var/log/apt/history.log

    Share any specific error messages for further diagnosis.

Report a Bug:

    If the issue seems like a repository or package bug in Ubuntu 25.10, report it:
    text

        ubuntu-bug update-manager

        Check Launchpad (https://bugs.launchpad.net/ubuntu/+source/update-manager) for similar reports.
    Consider a Fresh Install:
        If the upgrade from 25.04 to 25.10 has caused too many dependency issues, a fresh install of 25.10 may be cleaner. Back up your data first (e.g., to an external drive or cloud storage), then reinstall using a 25.10 ISO from https://ubuntu.com/download.

Why This Happened

The upgrade from 25.04 to 25.10 likely left some packages in an
inconsistent state, especially since 25.04 was an interim release. The
libwebkit2gtk-4.1-0 dependency conflict suggests a mismatch between
available library versions and what ubuntu-release-upgrader-gtk expects,
possibly due to repository changes or partial upgrades. Ubuntu 25.10
uses newer versions of GNOME and WebKitGTK, which may not align
perfectly with packages carried over from 25.04.

Try these steps and let me know the output of any errors (e.g., from
sudo apt install update-manager or specific dependency failures). If you
can confirm whether the Software Updater launches at all or if the issue
is purely the missing icon, I can refine the solution further.

Title:
  After 25.04 to 25.10 upgrade, update-manager not working properly

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Here is what I sent to Grok, and the reply. I tried many of these, as
  you will see:

  I recently updated Ubuntu from 25.04 to 25.10. After doing this
  upgrade, one of my icons is missing. The "software updater", which is
  an A with a circle around it, is no longer there. Where did it go?

  
  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
  Description:	Ubuntu Questing Quokka (development branch)
  Release:	25.10

  
  2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
  ??

  3) What you expected to happen
  Wanted to see the updates come in on the software updater.

  4) What happened instead
  It is not working properly.


  The Software Updater (officially called "update-manager" in Ubuntu) is a standard application included by default in Ubuntu Desktop editions, including 25.10. It should appear in your applications overview (accessed via the Super key or Activities button) under the "Administration" category, with its icon being a blue circle around a white "A" (representing "updates available"). If it's missing after your upgrade from 25.04, this is likely due to one of a few common issues: an incomplete upgrade process, a missing or broken package, icon theme glitches, or a change in how the desktop environment handles pinned or visible apps.
  Quick Checks and Fixes

      Search for It in the Applications Menu:
          Press the Super key (Windows key) and type "software updater" or "update manager".
          If it appears in the search results but isn't showing in the grid or dock, it exists but may not be pinned or visible by default. Right-click it and select "Add to Favorites" to pin it to your dock.
      Launch It via Terminal to Verify:
          Open a terminal (Ctrl+Alt+T) and run:
          text

      update-manager

      If it launches successfully, the app is installed but the
  icon/shortcut is the issue. If it doesn't launch (e.g., "command not
  found"), proceed to reinstall it.

  Reinstall the Software Updater Package:

      Upgrades can sometimes fail to carry over certain packages cleanly. Run these commands in the terminal:
      text

      sudo apt update
      sudo apt install --reinstall update-manager

      This will reinstall the app without affecting your system. After
  it completes, search for it again in the applications menu or relaunch
  via terminal. Log out and back in (or reboot) if the icon still
  doesn't appear.

  Fix Icon or Desktop Integration Issues:

      Reset GNOME Extensions: Ubuntu 25.10 uses GNOME 49 (with Wayland as default), and extensions can glitch during upgrades, causing icons to vanish from the dock or overview. Install the Extensions app if needed (sudo apt install gnome-shell-extension-manager), then:
          Open Extensions > Go to the "Installed" tab.
          Disable all extensions, log out/in, then re-enable them one by one to identify any culprits.
          Alternatively, reset all extensions via terminal:
          text

      gnome-extensions reset

      Then log out and back in.

  Update Icon Cache: If the icon specifically is broken:
  text

      sudo gtk-update-icon-cache /usr/share/icons/hicolor

      Restart your session afterward.
      Check for Conflicting Themes: Go to Settings > Appearance and switch to the default "Yaru" theme temporarily to see if a custom theme is hiding the icon.

  Ensure No Upgrade Artifacts:

      Run a full system upgrade to catch any missed packages:
      text

          sudo apt update && sudo apt full-upgrade

          If you have third-party PPAs or snaps from 25.04, they might
  conflict—disable them temporarily in Software & Updates (which you can
  launch via software-properties-gtk in terminal).

  If It Still Doesn't Work

      Check if you're on the standard Ubuntu Desktop (GNOME). Run echo $XDG_CURRENT_DESKTOP in terminal—it should output "ubuntu:GNOME". If it's something else (e.g., due to a partial install), reinstall the full desktop:
      text

      sudo apt install ubuntu-desktop

      Search for bugs: Visit the Ubuntu Discourse forums or Launchpad and look for "update-manager icon missing 25.10". Upgrades from interim releases like 25.04 to 25.10 can occasionally skip UI elements.
      As a workaround, you can always update via terminal (sudo apt update && sudo apt upgrade) or use the "Software" app (GNOME Software) for graphical updates, which handles most of the same tasks.

  This should restore it—upgrades are generally smooth, but icon visibility is a frequent hiccup in GNOME-based releases. If you provide more details (e.g., error messages from terminal), I can refine the advice.

  This used to come up with a list of software to install, and you could check off which ones you wanted. It would tell you how much space it took, and the versions. I do not see this now.

  It sounds like you're describing the functionality of the Software Updater (update-manager) in Ubuntu, which typically shows a list of available updates for installed software, including package names, versions, and the size of the updates, allowing you to selectively install them. If this interface is no longer appearing after your upgrade to Ubuntu 25.10 and the icon is missing, it’s likely that the update-manager package is either not installed, corrupted, or misconfigured, or the desktop environment is not displaying it correctly. Let’s troubleshoot and restore this functionality.
  Steps to Resolve the Issue

      Verify Software Updater is Installed:
          Open a terminal (Ctrl+Alt+T) and run:
          text

      update-manager

      If it launches and shows the familiar interface (a list of updates
  with checkboxes, version details, and sizes), the app is installed but
  not appearing in your applications menu or dock. If it fails with an
  error (e.g., "command not found"), proceed to reinstall.

  Reinstall Software Updater:

      Run the following commands to ensure the package is properly installed:
      text

      sudo apt update
      sudo apt install --reinstall update-manager

      After reinstalling, try launching it again with update-manager. If
  it opens and shows the update list with checkboxes, versions, and
  sizes, the core issue is resolved. Now, we need to fix the icon
  visibility.

  Check for the Icon in the Applications Menu:

      Press the Super key (Windows key) and search for "Software Updater" or "Update Manager".
      If it appears in the search but not in the applications grid or dock, right-click it and select "Add to Favorites" to pin it to the dock, or drag it to your desired location.
      If it doesn’t appear in the search, the desktop file may be missing or corrupted. Create or restore it:
      text

  sudo nano /usr/share/applications/update-manager.desktop

  Ensure it contains (or create it with) the following:
  text

  [Desktop Entry]
  Name=Software Updater
  Comment=Show and install available updates
  Exec=update-manager
  Icon=system-software-update
  Terminal=false
  Type=Application
  Categories=System;Settings;

  Save (Ctrl+O, Enter, Ctrl+X) and run:
  text

      sudo chmod +x /usr/share/applications/update-manager.desktop
      sudo update-desktop-database

      Log out and back in, then search for it again.

  Check for GNOME Software Interference:

      Ubuntu 25.10 uses GNOME Software (gnome-software) alongside Software Updater, and sometimes the system defaults to GNOME Software for updates, which has a different interface (less detailed, no checkboxes for individual packages).
      To confirm you’re using Software Updater and not GNOME Software:
          Run update-manager in terminal to ensure you get the detailed interface with package lists, versions, and sizes.
          If GNOME Software is opening instead when you click updates, go to Settings > Software & Updates > Updates tab and ensure "Check for updates" is set to a regular interval (e.g., daily). This ensures update-manager is triggered for updates.
      If you prefer GNOME Software but want the detailed view, you may need to rely on update-manager explicitly or use terminal commands (apt list --upgradable to see available updates with versions).

  Fix Icon or Desktop Environment Issues:

      Icon Cache Issue: If the icon (blue circle with a white "A") is missing or broken:
      text

  sudo gtk-update-icon-cache /usr/share/icons/hicolor

  Log out and back in.
  GNOME Shell Glitch: Ubuntu 25.10 uses GNOME 49, and upgrades can disrupt shell extensions or icon rendering. Reset GNOME Shell settings:
  text

      dconf reset -f /org/gnome/shell/

      Then reboot. This resets the application grid and dock to defaults, which may restore the icon.
      Theme Conflict: Go to Settings > Appearance and switch to the default Yaru theme to rule out a custom theme hiding the icon.

  Alternative: Check Updates via Terminal:

      If the GUI is still not working, you can view the same information (package names, versions, sizes) in the terminal:
      text

  sudo apt update
  apt list --upgradable

  This lists all available updates with their current and new versions. To selectively install updates, use:
  text

      sudo apt install <package-name>

      For example, sudo apt install firefox to update only Firefox. This
  replicates the checkbox functionality of Software Updater.

  Verify Upgrade Integrity:

      Upgrades from 25.04 to 25.10 can sometimes leave packages in an inconsistent state. Run:
      text

          sudo apt update && sudo apt full-upgrade
          sudo apt autoremove
          sudo apt autoclean

          This ensures all dependencies are resolved and stray packages are cleaned up.
      Check for Known Bugs:
          Search Ubuntu’s Launchpad (https://bugs.launchpad.net/ubuntu) or the Ubuntu Discourse forums for "update-manager missing 25.10" or "software updater no icon". This can reveal if others are experiencing the same issue post-upgrade.
          If you suspect a bug, consider reporting it with ubuntu-bug update-manager in the terminal to help the community diagnose it.

  Additional Notes

      Snap vs. APT: Ubuntu 25.10 uses a mix of APT (deb packages) and Snap for software. Software Updater handles APT updates, while Snap updates are managed by snap refresh or GNOME Software. To see Snap updates:
      text

  snap refresh --list

  If you’re expecting Snap package details in the updater, you’ll need to use GNOME Software or the terminal, as update-manager doesn’t list Snaps.
  Fallback to GNOME Software: If you can’t restore Software Updater, GNOME Software (gnome-software) can handle updates but with less granularity (no checkboxes or detailed size/version info). Launch it via:
  text

      gnome-software

      Go to the Updates tab to apply updates.

  If It’s Still Missing

  If none of these steps restore the Software Updater with its detailed
  interface:

      Confirm your desktop environment with echo $XDG_CURRENT_DESKTOP. It should say ubuntu:GNOME. If it’s different, you may have a partial desktop install. Reinstall the full Ubuntu desktop:
      text

      sudo apt install ubuntu-desktop

      Provide more details (e.g., any errors when running update-
  manager, whether GNOME Software is showing updates, or if you use a
  custom desktop setup), and I can tailor further steps.

  This should get you back to the familiar Software Updater interface with the list of updates, checkboxes, versions, and sizes. Let me know how it goes or if you hit specific errors!

                    Depends: ubuntu-release-upgrader-gtk but it is not going to be installed
                    Depends: update-notifier
  Error: Unable to satisfy dependencies. Reached two conflicting decisions:
     1. ubuntu-release-upgrader-gtk:amd64 is selected for install because:
        1. update-manager:amd64=1:25.04.5 is selected for install
        2. update-manager:amd64 Depends ubuntu-release-upgrader-gtk
     2. ubuntu-release-upgrader-gtk:amd64 Depends gir1.2-webkit2-4.1
        but none of the choices are installable:
        - gir1.2-webkit2-4.1:amd64 is available in versions 2.48.3-1ubuntu2, 2.48.6-1ubuntu1
          but none of the choices are installable:
          - gir1.2-webkit2-4.1:amd64=2.48.3-1ubuntu2 Depends libwebkit2gtk-4.1-0 (= 2.48.3-1ubuntu2)
            but none of the choices are installable:
            - libwebkit2gtk-4.1-0:amd64=2.48.3-1ubuntu2 is not selected for install
          - gir1.2-webkit2-4.1:amd64=2.48.6-1ubuntu1 is not selected for install

  The error you're encountering indicates that update-manager cannot be installed or reinstalled due to unmet dependencies, specifically gir1.2-snapd-2, ubuntu-release-upgrader-gtk, and update-notifier. The root of the issue seems to be a dependency conflict with ubuntu-release-upgrader-gtk, which requires gir1.2-webkit2-4.1, but the available versions of gir1.2-webkit2-4.1 (2.48.3-1ubuntu2 or 2.48.6-1ubuntu1) have their own dependency issues, particularly with libwebkit2gtk-4.1-0. This is a common issue after an Ubuntu upgrade (e.g., from 25.04 to 25.10), as package repositories or dependency chains can become misaligned. Let’s resolve this step-by-step to restore the Software Updater and its icon.
  Steps to Fix Unmet Dependencies

      Update Package Lists:
          Ensure your package lists are up-to-date to rule out stale repository data:
          text

  sudo apt update

  If you get errors about missing or unreachable repositories, check your sources in /etc/apt/sources.list and /etc/apt/sources.list.d/. Ensure they point to Ubuntu 25.10 (Oracular Oriole) repositories. For example:
  text

      deb http://archive.ubuntu.com/ubuntu/ oracular main restricted universe multiverse
      deb http://archive.ubuntu.com/ubuntu/ oracular-updates main restricted universe multiverse
      deb http://security.ubuntu.com/ubuntu/ oracular-security main restricted universe multiverse

      Edit with sudo nano /etc/apt/sources.list if needed, then run sudo
  apt update again.

  Fix Broken Dependencies:

      Run the following to attempt automatic dependency resolution:
      text

      sudo apt install -f

      This command tries to fix broken or missing dependencies by
  installing or removing conflicting packages. If it reports specific
  conflicts, note them for the next steps.

  Install Missing Dependencies Explicitly:

      The error mentions gir1.2-snapd-2, ubuntu-release-upgrader-gtk, and update-notifier. Try installing them individually to identify the root issue:
      text

  sudo apt install gir1.2-snapd-2
  sudo apt install ubuntu-release-upgrader-gtk
  sudo apt install update-notifier

  If any fail, the error output will point to the specific conflict. For example, ubuntu-release-upgrader-gtk depends on gir1.2-webkit2-4.1, which depends on libwebkit2gtk-4.1-0. Try installing the specific version mentioned:
  text

  sudo apt install libwebkit2gtk-4.1-0=2.48.3-1ubuntu2
  sudo apt install gir1.2-webkit2-4.1=2.48.3-1ubuntu2

  If version 2.48.3-1ubuntu2 fails, try the alternative:
  text

      sudo apt install libwebkit2gtk-4.1-0=2.48.6-1ubuntu1
      sudo apt install gir1.2-webkit2-4.1=2.48.6-1ubuntu1

  Clean Up Package Cache and Remove Conflicts:

      Clear out any corrupted or partial packages:
      text

  sudo apt clean
  sudo apt autoclean
  sudo apt autoremove

  If a specific package is causing conflicts (e.g., libwebkit2gtk-4.1-0), try removing it temporarily (if it’s not critical) and reinstalling:
  text

      sudo apt remove libwebkit2gtk-4.1-0
      sudo apt install update-manager

  Check for Held or Locked Packages:

      Sometimes, packages are held back, causing dependency issues. Check for held packages:
      text

  dpkg --get-selections | grep hold

  If any packages are listed, unhold them:
  text

  sudo apt-mark unhold <package-name>

  Then retry installing update-manager:
  text

      sudo apt install update-manager

  Force Installation of Compatible Versions:

      If the specific versions of libwebkit2gtk-4.1-0 or gir1.2-webkit2-4.1 are unavailable or conflicting, you can try forcing a compatible version. First, check available versions:
      text

  apt-cache policy libwebkit2gtk-4.1-0
  apt-cache policy gir1.2-webkit2-4.1

  If a compatible version exists in the repository, install it explicitly:
  text

      sudo apt install libwebkit2gtk-4.1-0=<version>
  gir1.2-webkit2-4.1=<version>

      Replace <version> with a version from the apt-cache policy output
  that matches your system’s architecture (amd64).

  Reinstall the Full Ubuntu Desktop:

      If the dependencies are too tangled, reinstalling the Ubuntu desktop environment can resolve missing or broken system components:
      text

      sudo apt install ubuntu-desktop

      This pulls in update-manager, update-notifier, and their
  dependencies, ensuring a consistent setup for Ubuntu 25.10’s GNOME 49
  environment.

  Check for Third-Party Repositories or PPAs:

      Third-party PPAs from Ubuntu 25.04 may be causing conflicts in 25.10. List your PPAs:
      text

  ls /etc/apt/sources.list.d/

  If any PPAs are present, disable them temporarily:
  text

      sudo mv /etc/apt/sources.list.d/<ppa-file> /etc/apt/sources.list.d/<ppa-file>.bak
      sudo apt update

      Then retry installing update-manager.

  Verify Snap Integration:

      The dependency gir1.2-snapd-2 relates to Snap package integration. Ensure the Snap daemon is installed and running:
      text

  sudo apt install snapd
  sudo systemctl enable --now snapd

  Then retry:
  text

      sudo apt install gir1.2-snapd-2

  Restore Software Updater Icon and Functionality:

      Once the dependencies are resolved and update-manager installs successfully, ensure the desktop file is present:
      text

  sudo nano /usr/share/applications/update-manager.desktop

  Verify or add:
  text

  [Desktop Entry]
  Name=Software Updater
  Comment=Show and install available updates
  Exec=update-manager
  Icon=system-software-update
  Terminal=false
  Type=Application
  Categories=System;Settings;

  Save, then update the desktop database:
  text

  sudo chmod +x /usr/share/applications/update-manager.desktop
  sudo update-desktop-database

  Update the icon cache:
  text

      sudo gtk-update-icon-cache /usr/share/icons/hicolor

      Log out and back in, then search for "Software Updater" in the
  applications menu. Launch it to confirm it shows the list of updates
  with checkboxes, versions, and sizes.

  Fallback: Use Alternative Update Tools:

      If update-manager still won’t install, you can manage updates via the terminal or GNOME Software:
          Terminal:
          text

  sudo apt update
  apt list --upgradable
  sudo apt upgrade

  This lists packages with versions and sizes, similar to Software Updater, though without a GUI checkbox interface.
  GNOME Software:
  text

  gnome-software

  Go to the Updates tab. It’s less detailed but can apply updates.
  Synaptic Package Manager (if you prefer a GUI with detailed control):
  text

              sudo apt install synaptic
              synaptic

              Synaptic allows you to see and select individual package
  updates with version and size details.

  If Problems Persist

      Check Logs for Specific Errors:
          Review APT logs for more clues:
          text

      cat /var/log/apt/term.log
      cat /var/log/apt/history.log

      Share any specific error messages for further diagnosis.

  Report a Bug:

      If the issue seems like a repository or package bug in Ubuntu 25.10, report it:
      text

          ubuntu-bug update-manager

          Check Launchpad (https://bugs.launchpad.net/ubuntu/+source/update-manager) for similar reports.
      Consider a Fresh Install:
          If the upgrade from 25.04 to 25.10 has caused too many dependency issues, a fresh install of 25.10 may be cleaner. Back up your data first (e.g., to an external drive or cloud storage), then reinstall using a 25.10 ISO from https://ubuntu.com/download.

  Why This Happened

  The upgrade from 25.04 to 25.10 likely left some packages in an
  inconsistent state, especially since 25.04 was an interim release. The
  libwebkit2gtk-4.1-0 dependency conflict suggests a mismatch between
  available library versions and what ubuntu-release-upgrader-gtk
  expects, possibly due to repository changes or partial upgrades.
  Ubuntu 25.10 uses newer versions of GNOME and WebKitGTK, which may not
  align perfectly with packages carried over from 25.04.

  Try these steps and let me know the output of any errors (e.g., from
  sudo apt install update-manager or specific dependency failures). If
  you can confirm whether the Software Updater launches at all or if the
  issue is purely the missing icon, I can refine the solution further.
