repo keys fail

[Gene Heskett <gheskett@shentel.net>]

Greetings;

My last installation of wheezy has developed a key failure when trying to 
run package-manager or synaptic-pkexec, so it is not getting all the 
updates.

What is the cli command, presumably prefaced with a sudo, that will fetch 
and refresh these changed keys?  "sudo apt-key update" does not update 
anything.

sudo apt-get update
ends with this:
W: Failed to fetch http://http.debian.org/debian/dists/wheezy/Release.gpg  
Could not resolve 'http.debian.org'

W: Some index files failed to download. They have been ignored, or old 
ones used instead.

Solution?

Thanks.

Cheers, Gene Heskett
