As I mentioned in my intial post, there are several topics about this problem.
But one of them is an Announcement, so should be read:
All this stuff is the result of Arch packaging renaming activities for KDE, which have been promptly handled by Garuda with the garuda-update package.
All the rest, for example the bunch of packages to be removed here, are due to AUR packages not promptly updated by their maintainers according to the renamings above.
None of these are in the responsibility of the Garuda team or manageable in a different way.
The “bugs” must be due to something else, and should be addressed with proper and specific topics (garuda-inxi, logs, etc.), otherwise nothing can be fixed.
