I have found this to be true on Kubuntu 26 and Debian Trixie. Kubuntu will start the first time and maybe (not always) the second time but if I go to use it for a third time, there is usually no start. Just nothing appears on the screen. If anything, Discover has been a problem at times for longer than I care to think. I normally use terminal commands to update & upgrade but I have noticed that Discover has had problems for years. Synaptic Package Manager never exhibits problems.
When this happens, is it still running in the background?
ps -ef | grep discover will tell you.
Yes it is normally running in the background. One time I did try (using htop) to kill the PID and restart Discover but it didn’t work.
Right now it won’t start and here is the response from your suggested command
kub2john 6917 920 32 10:41 ? 00:00:11 /usr/bin/plasma-discover
kub2john 6947 920 0 10:41 ? 00:00:00 /usr/lib/x86_64-linux-gnu/libexec/kf6/kioworker /usr/lib/x86_64-linux-gnu/qt6/plugins/kf6/kio/kio_http.so https local:/run/user/1000/discovernVfqDN.1.kioworker.socket
kub2john 7210 7198 0 10:41 pts/1 00:00:00 grep --color=auto discover
kub2john@kub2john-5201020:~$ ^C
Yeah, that’s the problem. And this is a bug, so we need to get to the bottom of it!
In your terminal output kill 6917 should fix the problem. Should it fail, try kill -9 6917.
Is the bug 100% reproducible? As in, literally every time you close Discover’s window, /usr/bin/plasma-discover remains running in the background?
The kill 6917 worked, Discover started. I closed Discover and it won’t start.
kub2john@kub2john-5201020:~$ ps -ef | grep discover
kub2john 7438 920 1 10:50 ? 00:00:04 /usr/bin/plasma-discover
kub2john 7474 920 0 10:50 ? 00:00:00 /usr/lib/x86_64-linux-gnu/libexec/kf6/kioworker /usr/lib/x86_64-linux-gnu/qt6/plugins/kf6/kio/kio_http.so https local:/run/user/1000/discoverZSeBqc.1.kioworker.socket
kub2john 7618 7198 0 10:54 pts/1 00:00:00 grep --color=auto discover
So this time kill 7438 worked.
I’m going to say this is a repeatable bug.
Excellent! Repeatable bugs can be identified and fixed.
So here’s what I want you to do. Run plasma-discover --listbackends. That will give you output like this:
available backends:
* flatpak-backend
* fwupd-backend
* kns-backend
* packagekit-backend
I want you to run plasma-discover --backends [one of those items]. Then close the window and see if plasma-discover is still running in the background.
This is to identify which backend is getting stuck. I’m going to hazard a guess that it’ll end up being kns-backend, because it’s been that in the past. But we have to figure out which one it is for you!
If running Discover with one backend at a time fails to produce a dangling process running in the background, try running with two at a time (separate them with commas). For example, plasma-discover --backends packagekit-backend,kns-backend.
kub2john@kub2john-5201020:~$ plasma-discover --listbackends
Available backends:
* fwupd-backend
* flatpak-backend
* kns-backend
* packagekit-backend
* snap-backend

Cool, that’s how you do it. Let me know when you find the backend (or combination of backends) that makes plasma-discover fail to fully quit when you close its window.
Hm? Ok, DIscover won’t start. SHould I kill it again and start over. I got lost at this last request. Not sure what I am looking for??? I killed Discover and then did this and it started Discover. I closed Discover, the terminal is still open. Sadly I have to go and will be back later and we can continue.

I’m asking you to perform a loop of the following:
- Launch Discover with a specific backend or combination of backends.
- Close its window from the close button.
- See if the
plasma-discoverprocess exited cleanly (did it return you to the shell?). - If it did exit cleanly, try another combination.
- If it remained running after closing the window, that’s one of the backends or combination of backends that causes the problem for you!
Started it and closed Discover using the close button. It didn’t being back to the shell without a lot of messages and it is still an open shell. kub2john@kub2john-5201020:~$ plasma-discover
