The website appears to be either down or misconfigured, I can't get to it either. –  Jorge Castro Feb 16 '11 at 14:30

When you add a third-party repository, you should also add its key to your system. The public key is a string which identifies that certain repository. You can find some more information on this and how to add the key here.

Run the following in your terminal,

 sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3C962022012520A0 
 sudo apt-get update

References: How do I fix the GPG error "NO_PUBKEY"?

You need to replace the key (3C962022...) with the one that is displayed in the error message in the terminal.
