  <compulsory_for_desktop>Unity</compulsory_for_desktop>
  <compulsory_for_desktop>XFCE</compulsory_for_desktop>

I can confirm that the compulsory_for_desktop tag is present in
PackageKit version 1.2.8-2ubuntu1.2 from the noble-proposed repository.
I can also confirm that "PackageKit" is no longer uninstallable in
AppStream-based software centers such as GNOME Software or KDE Discover
(it is still uninstallable in App Center, but that is a different
issue).

Thanks!

Title:
  AppStream metadata allow user uninstallation of PackageKit

Status in PackageKit:
  Fix Released
Status in packagekit package in Ubuntu:
  Fix Released
Status in packagekit source package in Noble:
  Fix Committed

Bug description:
  [ Impact ]

  An AppStream metainfo file was added in PackageKit since v1.2.8.
  Unfortunately, this file causes PackageKit to show in App Center,
  GNOME Software, KDE Discover and other package management GUIs and
  allow users to click an "Uninstall" button.

  The appstream metadata should be updated to specify that it cannot be
  uninstalled. This was implemented upstream in version 1.3.0:
  https://github.com/PackageKit/PackageKit/commit/d8f84f7e0a017e0b4df1e08a2a6be832c9fb3611

  [ Test plan ]

  1. Install gnome-software
  2. Run `gnome-software --details org.freedesktop.PackageKit`
  3. Verify that "Software" opens a page about PackageKit
  4. Verify that there is no button to uninstall it

  [ Where problems could occur ]

  The patch only changes the metainfo.xml file adding
  <compulsory_for_desktop> tags. The tag is supported starting from
  appstream version 0.6 (dating 2014), so the file will be parsed
  without problems.
