I have a problem with PolicyKit, when I try to install programs in Ubuntu software-center (similar messages in synaptic or muon): The problem started after upgrade from 13.04 to 13.10.

When I try to remove / install programs I get notification:

You are not allowed to perform this action!

You don't have the required privileges to perform this action

When you open details you see this:

org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.44'}): org.debian.apt.install-file

I already checked:

• Policy kit is present in autostart, so that is not the problem.


• When I log in as root user (instead of user account that I regulary use) I have no problems.


• This is the generated error report in /var/crash/


• Maybe related bug

I also tried to add my user to the group root, now my user is in these groups

adm dialout cdrom sudo audio plugdev staff users fuse lightdm mlocate netdev bluetooth lpadmin admin sambashare kismet root

What exactly are the rights, I need to be able to access the software center as user?

Also related to

"Software can't be installed or removed because the authentication service is not available. "

EDIT:

Maybe this problem has to do with it that I also cannot mount USB-devices since the upgrade if I start nautilus as the normal user.

I have to start withgksudo nautilus to be able to mount the USB-stick with the button on the left side (as root then)

Maybe it has to do something with the packages installed, here is the output of dpkg -l
