Ubuntu – “Authentication service is not available” when installing IDLE (using python 2.7)

idle-pythonpythonsoftware-center

I am getting this error installing IDLE on 12.10:

Software can't be installed or removed because the authentication service is not available.
(org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.95'}): 
org.debian.apt.install-or-remove-packages

I can't install anything, even games. They all come up with the same error message.

Is there something I am missing? Please suggest.

A temporary workaround to this is:

sudo software-center
