Hi,
I have recently upgraded from FC20 to FC21 using fedup - it was a
pleasantly smooth upgrade......
However..... I do not appear to be being notified of any pending package
updates (maybe there arent any? - doubtfull!)..
And so (using KDE) I am trying to run system-config-services to check
packagekit. (although the command line systemctl tells me packagekit.service
is running).
When I attempt to run kde->administration->service-management I get no window.
When I run system-config-services from the command line I get:

Same thing if I run it under sudo.
Is this a dbus problem?
have I got some other problem with my system config?
Am I just being stupid?
Any clues?
Many Thanks
