Description of problem: kpackagekit apparently blocks the yum backend and it is entirely non-obvious how to disable it in the kde-desktop. Only way to disable it that worked for me was removing it with "rpm -e", however a more fine-grained approach (eg per user config) would be nice. Just because I prefer other packaging tools should not force system-wide uninstallation. Up to date Fedora 12 How reproducible: see https://bugzilla.redhat.com/show_bug.cgi?id=568766
This is not a bug, its just how the system works. Kpackagekit and yum are both package managers and while one is running the other is locked out. Steven M. Parrish KDE & Packagekit Triager Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
so how do I stop it without uninstalling it? Sorry about the dumb question but is not obvious.
It can be disabled in System Settings / Advanced User Settings / Service Management.
