Details

Since updating last night (Using testing repos and not kde-unstable), the applications menu and task bar shows no applications.

The apps pinned to the task bar show up as white blank icons, and attempting to click them results in a error of "Unknown application folder".

Applications will launch fine if launched from the terminal, but their icons do not show up on the task bar.

I tried to delete files in ~/.config/menus, and that has done nothing.

Also, kmenuedit appears broken. When trying to add anything, the UI remains blank and does not add a new entry.

Package versions and system details:

System: System76 Oryp8
DE: Plasma 5 on both Wayland + X11 (Both have the same issue)
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.11
KDE plasma version: 5.27.8
This task depends upon

kbuildsycoca5 running...
"applications.menu" not found in ("/home/rnd_ash/.config/menus", "/etc/xdg/menus")

Again, after rebooting, nothing changes

Looks like something is badly broken with your desktop database. I'd suggest to take this to the Arch or KDE support channels.
Comment by Ashcon Mohseninia (rnd_ash) - Tuesday, 17 October 2023, 09:55 GMT
This has been reported by a few people over on Reddit, hence why i created this issue, so i don't think it is as simple as a broken desktop database, as mentioned. This only started to happen after an update
Comment by Antonio Rojas (arojas) - Tuesday, 17 October 2023, 10:01 GMT
Can you please link to those reports?
Comment by Antonio Rojas (arojas) - Tuesday, 17 October 2023, 10:04 GMT
Please also attach the pacman log of the transaction that caused this.
Comment by Ashcon Mohseninia (rnd_ash) - Tuesday, 17 October 2023, 10:06 GMT
After commenting out extra-testing in pacman.conf, and running

aru -S $(pacman -Qq) --overwrite "*"

it appears to be working. Ill do a fresh test with the extra-testing repo enabled

1 other user [1]? FWIW, cannot repro here.
