Description Pornpipat Popum 2025-12-04 21:13:24 UTC 
SUMMARY
I've noticed that in the PackageKit plugin, it is specifically hardcoded to deny it from being used when /run/ostree-booted exists. https://invent.kde.org/plasma/discover/-/blob/master/libdiscover/backends/PackageKitBackend/PackageKitBackend.h#L90

I have recently written a PackageKit backend to specifically support bootc-based images for updating over PackageKit (https://github.com/FyraLabs/PackageKit-bootc), and Discover refuses to start and crashes outright, considering the plugin invalid due to /run/ostree-booted existing, making updates over PackageKit impossible.

STEPS TO REPRODUCE
1. Install PackageKit-bootc and the PackageKit backend
2. Attempt to run Plasma Discover

OBSERVED RESULT
The PackageKit backend gets rejected and the application crashes

EXPECTED RESULT
Discover loads the PackageKit backend

If you remove that check, does everything work?

Yes, reverting commit b7ed897e6842002b195c02c6e89f4e06aee12d09 (https://invent.kde.org/plasma/discover/-/commit/b7ed897e6842002b195c02c6e89f4e06aee12d09), and using the new PackageKit bootc plugin, everything works as intended.
