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

Try this:

sudo apt-get update
sudo apt-get install idle3

Also, it is possible your package manager is being blocked by another process, like an update in the background, or another install that did not complete. You can try rebooting, and then issuing the following, which will finish any incomplete installations:

sudo dpkg --configure -a

thanks for all your help

i can't get mine working, i tried Da1t's suggestion with no luck. i had the software center working when i ran it as:

sudo software-center.

but that's hardly a permanent solution.
