No Updates do to bad SIG?

[nitricacid]

Ever since I updated to Breezy Full I have been getting this error when ever I do a 'Sudo apt-get update' in a terminal
Fetched 379B in 1s (249B/s)
Reading package lists... Done
W: GPG error: http://us.archive.ubuntu.com breezy Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

Here is my sources.list:

My question(s):
1. Has there been any updates since the full Breezy release?
If so could my BADSIG error being hindering my updates?
2. How do I fix this BADSIG error?

Per cytoplasm in the thread here (http://www.ubuntuforums.org/showthread.php?t=78033)...

Remove the "us" references in the URL within the sources.list file and then run update again. It will then work correctly.
