Description geisserml 2021-04-30 15:16:49 UTC

SUMMARY
I by mistake locked/pinned konsole and konsole-part and find no way to revert this. Opening the context menu and clicking on "Unlock package" will trigger a pop-up explaining the package could not be locked.

STEPS TO REPRODUCE (potentially dangerous)
1. Pin a package in Muon (right-click -> lock at current version)
2. Try to unlock it again
-> A popup will show up that says "Failed to lock package"
I assume Muon is trying to lock already locked packages rather than unlock them, at least the behaviour indicates this.

OBSERVED RESULT
It is not possible to unlock packages. The context menu option fails.

EXPECTED RESULT
It should be possible to unlock locked packages. This is important as it could break system updates if one accidentially locked a package (like me).

It would be important if at least someone could tell how to manually revert locking a package (e. g. from command-line or via another package manager), since this issue could potentially break system updates.

Now found out how to manually revert the lock:
go to /etc/apt/preferences.d/ and delete the problematic files (konsole and konsole-kpart in my case)

Closing as I'm not using muon anymore.
