Hi, Since the start of the F12 development cycle authentication in kpackagekit is broken (due to the transition to PolicyKit1?). Bug report [1] shows the issue. Gnome packagekit seems to be working as can be seen in bug report [2]. As a temporary work around one can use: 1) yum at the command prompt 2) gnome packagekit and gnome-authentication-agent Is it an idea to enable gnome-packagekit as long as the kpackagekit issue isn't solved? Some other thoughts? Thanks, Martin Kho Bug [1]: https://bugzilla.redhat.com/show_bug.cgi?id=509136 Bug [2]: https://bugzilla.redhat.com/show_bug.cgi?id=499968
