Im getting that as well:
W: GPG error: http://archive.ubuntu.com breezy Release: The following 
signatures were in valid: BADSIG 40976EAF437D05B5 Ubuntu Archive 
Automatic Signing Key <ftpmaster at ubuntu.co m>
W: You may want to run apt-get update to correct these problems
wadesmart at wadesmart:~$


I tried the restore default keys but that didnt work.

Any more ideas?

Wade
