STEPS TO REPRODUCE
1. Log in

OBSERVED RESULT

EXPECTED RESULT

(available in About System)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0

Fetching updates with dnf works fine.

Opening discover from command line shows:

adding empty sources model QStandardItemModel(0x560dd7916170)

Does it ever succeed? If it did, how long did it take? If not, how long did you let it wait for before giving up and reporting this bug?

Comment 2 Eduardo Sánchez Muñoz 2023-10-25 16:51:02 UTC

First, I waited around 20 minutes before giving up. After a reboot, I tried again and gave up after 5 minutes and updated with dnf, which took much less times.

I think I've see packagekit-dnf getting stuck once before...
In any case these should help https://bodhi.fedoraproject.org/updates/FEDORA-2023-e2962fcb2a - https://bodhi.fedoraproject.org/updates/FEDORA-2023-f356f702f4 simply because they reduce the stuff that needs to be downloaded for a refresh

Comment 4 Nate Graham 2023-10-26 21:15:19 UTC

That would make sense. Let's re-evaluate in Plasma 6 which includes your other changes too. FWIW I don't get super long load times anymore in Plasma 6.
