[RESOLVED] After botched 24.04 update, plasma-discover won't load

[pwlinwin]

I performed the upgrade to 24.04 today, as per the GUI notification. Unfortunately, the computer black screened right in the middle of it and botched the install.

I managed to reboot, but network.services didn't come back up. It turned out I was missing dependencies, and I couldn't repair it via apt-get because there was no network. I ended up having to tether my phone via USB and using dchclient to get internet long enough to use apt-get to --fix-broken everything. I then restarted again and that got my network back, so tried the 24.04 upgrade again via the gui, but it loaded with a blank error message. So I just did an "apt-get update" and "apt-get upgrade" on the system, and after a lot of waiting it seemed to get me to a stable 24.04 install (according to the system information window).

One problem. plasma-discover won't load. There is the update icon in the taskbar, but when I click on it nothing happens. Discover won't load from the application menu. When I load plasma-discover in the console, it appears to run, but generates no output and just hangs.

Other than that, everything else seems to be working okay.

Did you try a new user account? If Discover works there the culprit are user cache or/and settings files.

I found it was running in system monitor. So I killed it.

When I run it again in console I get:

fetch ratings! true
adding empty sources model QStandardItemModel(0x64401f001380)

Then it just hangs.

Any way to clear the cache?

Well, i managed to get discover to load once upon a reboot. I updated a whole pile of packages through the discover prompts, then rebooted. I'm back to not being able to run Discover again. Also, the syncthing desktop ui isn't running anymore. The service is running, and the web ui works, but the desktop gui won't load. Disregard. Syncthing-Gtk just uninstalled as part of the update apparently.

Everything else seems to work,.

UPDATE: Drivers are missing from system-settings. Not sure if they got moved or depreciated. Ubuntu-Drivers is no longer installed. Not sure if that is normal now. I always just manually installed the nvidia drivers manually via apt because the gui drivers tool stopped updating a while ago, but its odd it is totally gone now.

Found the resolution to this on another thread, here.

It was removing snap that fixed it.

sudo apt purge plasma-discover-backend-snap

. Thanks to Schwarzer Kater. Please mark this as resolved.
