I cannot seem to find a link to software sources in discover after the update to Kubuntu 22.04.Also only firmare, snap and flatpak are displayed as sources. enter image description here

    Do you have `software-properties-qt` installed in your system? That's the program the `software sources`-button opens on my system. – mook765 Apr 28 '22 at 09:33
  • What happens if you select "Add source"? – cipricus Apr 28 '22 at 09:33
  • After creating a new desktop file in `usr/share/applications` called `software-properties-kde` (beside the `software-properties-qt` already present - for the purpose of fixing a Muon problem discussed in comments under [here](https://askubuntu.com/q/1404500/925128)), on my system I have 2 "Software Sources"in Discover, which confirms that those buttons are links to desktop files in `usr/share/applications`. Corresponding tools like `software-properties-qt` need to be installed. Do you have that installed? Do you have the file `/usr/share/applications/software-properties-qt.desktop`? – cipricus Apr 28 '22 at 09:44
  • I have `software-properties-qt` installed, though not `software-properties-kde` installed. – Bruni Apr 28 '22 at 10:09
  • I also am unable to install software-properties-kde due to dependency issues. – Bruni Apr 28 '22 at 10:13
  • @cipricus I have the file /usr/share/applications/software-properties-qt.desktop and I have edited it as suggested in the comments to the other question. Also: when I press add source I can add an additional flatpak repo.... – Bruni Apr 28 '22 at 10:15
  • `software-properties-qt` is what you need and what you should have accessible from Discover. If there is no other way, simply make it accessible separately as indicated under the other Q. – cipricus Apr 28 '22 at 16:59
  • @cipricus I have it installed and it is accessible separately (so I do not have a real usability problem). Thank you. – Bruni Apr 29 '22 at 09:49

Same issue here, this solved it for me:

Run Discover, go to the settings page, then view your journalctl (run journalctl in console and hit the End key to jump down).

That showed an error for an improperly formatted file in /etc/apt/sources.list.d/ from a release upgrade. After removing the broken source, Discovery shows the sources now.

  • Interesting. Though, my sources.list.d seems fine (no error messages in journalctl and no error messages when running apt-get update. – Bruni May 30 '22 at 06:51
