I just installed KDE, and every time I run the Software Updates program it says:
This operation cannot continue since proper authorization was not provided.
How can I get it to work?
Earlier : Ubuntu 11.10 with KDE installed does not prompt for elevation for privileged ops in all apps
Few bug reports:
Muon-updater doesn't ask for password / https://bugs.launchpad.net/ubuntu/+source/qapt/+bug/833058
Kubuntu desktop missing dependency on polkit-kde-1 / https://bugs.launchpad.net/ubuntu/+source/policykit-1-gnome/+bug/867737
Do you have the polkit-kde-1 installed ?
The polkit-kde-1:
PolicyKit-Kde provides a D-Bus session bus service that is used to bring up authentication dialogs used for obtaining privileges.
sudo apt-get install polkit-kde-1
did not fix it for me (Kubuntu 12.10), but this did:
sudo apt-get -f install
It also showed that I had a bunch of packages with unmet dependencies. I had just run a bunch of updates with Muon and rebooted, but apparently it did not pick up all the dependencies.
