How can I "provide proper authorization" to the KDE Software Updates program?

Question

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?

Answer 1

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.

Answer 2

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.
