[Bug 2077969] Re: Settings > Ubuntu Desktop > "No Ubuntu settings found"

[Kevin]

Thank you @vanvugt ! I got my desktop icons and dock back in their same
relative positions as before my upgrade. This was after re-installing
gnome-shell-ubuntu-extensions per your recommendation and also re-
booting.

Bug description:
  [ Impact ]

  On upgrade to 26.04, the default Ubuntu Desktop gnome-shell extensions
  are not installed if the `ubuntu-desktop-minimal` metapackage was not
  present on the upgrading system.

  This manifests with missing desktop icons, enhanced tiling, and app-
  indicators, as well as with an empty Settings > Ubuntu Desktop page.

  The proposed solution is to add a dependency on `gnome-shell-ubuntnu-
  extensions` from the `ubuntu-session` package, which is the binary
  package providing the means to log-in to the Ubuntu desktop session.
  Previously instead, there was only a dependency on the extensions
  package from the ubuntu-desktop{,-minimal} metapackages.

  [ Test Plan ]

  1. Set up a 24.04 or 25.10 Ubuntu Desktop install
  2. Remove the ubuntu-desktop and ubuntu-desktop-minimal metapackages
     -> this should mark all direct dependants as manually installed, rather than
        removing them as unused
  3. Upgrade to 26.04
  4. Verify that desktop icons, enhanced tiling and app-indicators are available
  5. Verify that Settings > Ubuntu Desktop is available

  [ Where problems could occur ]

  Removing gnome-shell-ubuntu-extensions will now require removing the
  ubuntu-session package as well. This is intended: if the user wants to
  use gnome without the ubuntu extensions they can use the `gnome-
  session` package instead (or disable the extensions instead of
  uninstalling them)
