    Discover does not show APT Repos

    Hello,
    I have the issue that one one of my 2 Machines (Both have Kubuntu 24.04, upgraded from 22.04, yet on one of them discover doesnt seem to list any APT Repos, which is kinda annoying for management, for the other one it seems to work tho. The Discover Version is 5.27.12 for both of them.

    I will bet one machine is an upgrade, the other a fresh installation?

    This is a known issue. Debian's apt has a new source file format, and Ubuntu started using it in either 23.10 or 24.04.
    Plasma's apt backend. or packagekit, or both, don't like the new format, and it still hasn't been fixed.

    It has been mentioned a few times here.
    A workaround is to replace the new file /etc/apt/sources.list.d/ubuntu.sources with the old style /etc/apt/sources.list, as well as doing something simillar for any PPAs and other wexternal repos.
    Notice that this also breaks the button in Discover for the Software Sources tool,

    Another more logical workaround is to get to the Software Sources tool manually (sudo software-properties-qt), or by going to the Driver Manager in System Settings. That entry simply opens the Software Sources tool focused on the drivers tab there.

      actually both should have been upgrades. as far as I remember the one on the left started at 2204 definitely (as it was installed january 2023 with the end of Windows 8), while the right one might have been 20.04 as that was installed mid-2022 before 2204 was fully out, although the one on the right was updated pretty recently due to me pushing the upgrades as I noticed the whole electron and 2204 issue on my home (left) machine and didnt wanna deal with it on my work box so I just pushed it and only did the upgrade some time this year.

      maybe the upgrade flow changed a bit.

        Upgrades or fresh installs wouldn't matter, the sources file text format changed in 24.04, and at least your main Ubuntu sources would have been switched over to this during the upgrade.

          what claydoh said.

          synaptic has a more granular interface for adding repositories if you don't have a full path to just paste into the driver manager.
