Created attachment 113616 [details] Packages held back marked as upgradeable See attached screenshot. apt won't let me upgrade 100 packages, but Discover will; the held-back packages are presented normally, and clicking on the Update All button upgrades them, with unknown consequences (surely there was a reason why they were held back?).
Possibly a bug in PackageKit. Can you check with "pkcon update"?
If you can provide the information requested in comment #1, please add it.
To further investigate this issue, KDE developers need the information requested in comment #1. If you can provide it, or need help with finding that information, please add a comment.
In order to provide the information Aleix has requested, I need another batch of updates to come in that `apt` doesn't want to apply, so I can issue `pkcon update` to see if PackageKit ignores those restrictions, or if it's Discover that ignores PackageKit (much less likely, but still possible I guess). No such problematic update has been offered, so I'm still waiting.
