I am using Ubuntu 12.04 and Awesome window manager. When I run software-center I cannot install or remove software. I get the following warning:

softwarecenter.backend - WARNING - _on_trans_error: org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name':  ':1.105'}): org.debian.apt.install-or-remove-packages

It worked just fine outside Awesome wm. I searched on google/askubuntu and found this post, which seemed to had the solution (gksudo software-center & exit).

Now I can install new software, but I can't view or search my installed software . The page just keeps showing the loading icon, but won't ever load. I don't get any warnings or errors.

Just to be clear, installing/removing/searching using synaptics/apt-get/dpkg works just fine.

The question, you mentioned, lists this behaviour as a bug. Please see bugs.launchpad.net/ubuntu/+source/software-center/+bug/1045186 – qbi Jan 21 at 9:59
Since this is a bug, this question will probably be closed as off-topic, in accordance with the FAQ and this policy. Please note that you can run Software Center with sudo rather than PolicyKit as a workaround (as stated in comments in the bug report). The best way to do that is usually to press Alt+F2 and run gksu software-center. – Eliah Kagan Jan 22 at 1:17
