plasma-discover updates cannot handle apt *.sources files

[Gordon Lack]

Recent additional software sources from launchpad (e.g. grub-customizer, kubuntu backports) drop *.sources files into /etc/apt/sources.list.d/.

It seems that plasma-discover cannot handle these. They do not show up in the list of configurable sources.

And, even worse than that, it seems that if you have sufficient *.sources files (I had 5 on a newly installed 23.10 system) the entire Default source section is absent from the plasma-discover Settings page! (I got it back by copying over the older, mostly *.list entries and keys from an older system).

PS: I've had to report the package here as "don't know" as the search doesn't recognize plasma-discover, and ubuntu-bug doesn't let me choose "Other problem" as an option (-> You need to specify a package or a PID. See --help for more information.)

please tell me sudo dpkg -l plasma-discover
 output. I cannot reproduce in Jammy with backports enabled. Mantic will not get anymore updates so I need to see if there is a patch... Seems like a huge bug to have slipped past qa though.

[Gordon Lack (gordon-lack)]

Note that this is being reported against mantic (23.10) so what Jammy can/cannot do is not really relevant.

The bit about the entire Default section disappearing seems to have sorted itself out, but the absence of any information about sources configured using *.sources files is still present.

This applies both to the list shown in "Settings/Default source" and the "Software Sources/Other Software" tab.

I'll attach the screenshots and the sources/list.d and trusted.gpg.d directories that led to them (these correspond to the same repositories, but Sources-1 just has 1 *.sources file (winehq) as it has been upgraded from Jammy with each 6-month release (just editing the release name in the *.list files) whereas Sources-5 is from a fresh install of Mantic on a new system with recent add-apt-repository runs (mostly form Launchpad), which now produces *.sources files.

The plasma-discover version is:

It seems to be the same on my side after the update to Ubuntu 24.04 (there is now the ubuntu.source also in this folder. With that I have also 5 files). The entire section is then not shown. (plasma-discover version: discover 5.27.11)

Hi, having the same issue.

This makes plasma-discover almost unusable under 24.04 .

For what reason the Bug has been marked Incomplete?

[Mike Burgener (mbgeversys)]

Confirmed by @thecrazygecko and @mbgeversys
