I upgraded to 12.10, and now I can't use Software Center or Network Administration. It keeps giving me an authentication errors. When I check /var/log/auth.log, I see:

Oct 31 21:10:45 mike polkit-agent-helper-1[4665]: pam_unix(polkit-1:auth): authentication failure; logname= uid=1000 euid=0 tty= ruser=root rhost=  user=root

I found a post which said to change my password, which I've done (both through the Ubuntu settings GUI tool, and through recovery mode. No avail.

Any suggestions?
