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?

Do you have kdesudo or kdesu installed? – devius Feb 11 '12 at 17:10
KDE Software Updates use PolicyKit, not kdesudo – Lekensteyn Feb 11 '12 at 17:40
Can we get a few more details? When does this error occur? After opening, after checking for updates, after telling them to install? Maybe a screenshot? – Huckle Feb 11 '12 at 18:02
Sorry about the misleading comment then. It's been a while since I used KDE. Then it's probably a PolicyKit policy problem. If that hasn't changed, policies can be edit in System Settings. – devius Feb 11 '12 at 18:02

Earlier : Ubuntu 11.10 with KDE installed does not prompt for elevation for privileged ops in all apps

Few bug reports:

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.

Thanks. sudo apt-get install polkit-kde-1 and rebooting fixed it. – Jon Feb 13 '12 at 18:26
I have added that package note to the KDE installing section on the wiki as it needs it so we need to note it. – Liam Dawe Jul 31 '13 at 10:27

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.
