I tried reinstalling, but it didn't help

Comment 1 Aleix Pol 2021-11-03 02:06:32 UTC

Can you please provide a backtrace or some more information? There's not much I can do with this. You should be able to get the backtrace from KCrash.

Comment 2 Fushan Wen 2021-11-03 03:20:21 UTC

Can you delete ~/.cache/discover and try again?

Comment 3 aronkvh 2021-11-03 15:00:46 UTC

Deleting  ~/.cache/discover didn't work.
the debugger in drkonqi can't generate info, quits unexpectedly

Comment 4 aronkvh 2021-11-03 22:04:22 UTC

Ksyslog shows this for the latest try, maybe it helps with something?

Comment 7 Aleix Pol 2021-11-10 01:40:41 UTC

Would you be able to build the Plasma/5.23 branch? I think I included a fix there today (614450b3ee9175fb16f068af505fb59ed27e6697). Or otherwise maybe wait until 5.23.4 gets released (yes, I'm sorry about that).

Otherwise, you'll be getting a 5.23.3 update soon, if you could provide a backtrace from it, that could also help.

Note that if you're unable to open discover because it crashes, you can use "plasma-discover --backends packagekit" that won't load the faulty backend.

Here's the backtrace after I updated

This behavior is deprecated.
You have to import QtQml 2.15 after any QtQuick imports and set
the restoreMode of the binding to fix this warning.
In Qt < 6.0 the default is Binding.RestoreBinding.
In Qt >= 6.0 the default is Binding.RestoreBindingOrValue.

A debugging session is active.

        Inferior 1 [process 122268] will be killed.

Quit anyway? (y or n) [answered Y; input not from terminal]

Comment 11 Aleix Pol 2021-11-11 17:22:38 UTC

I see the same backtrace on them all, are you sure they're different?

Do you have any disabled flatpak repositories?

Comment 12 James Cain 2021-11-17 14:59:24 UTC

Crashes here a few seconds after start-up as well. KDE Neon 5.23.3.

Seems to be either Flatpak or OpenDesktop-related (or both?). Here's console's output when run from terminal:

Could someone provide a workaround until it's fixed? managing apps without discover is much harder.

Comment 14 Diaa Sami 2021-12-09 13:18:13 UTC

I have the same problem for weeks, it was resolved by uninstalling "rpm-ostree".
Also I found out I can run plasma-discover and provide the backends, I assume this would work too but I haven't tried it.

plasma-discover (5.24.0) using Qt 5.15.3

Comment 17 Aleix Pol 2022-02-09 03:27:32 UTC

Would you be able to give us your `flatpak remote-list -d --show-disabled` output?

Comment 18 Diaa Sami 2022-02-09 10:00:00 UTC

Problem is still there for F35.
For me, since the problem is specifically with rpm-ostree, one solution is to remove rpm-ostree and the other is to launch discover with only specific backends (excluding rpmostree):
plasma-discover --backends $(plasma-discover --listbackends | grep -v rpmostree | sed -n '2,$s/[\\* ]//gp' | paste -s -d, -)
