GPG error: http://extras.ubuntu.com natty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192

I think I selected to install things from extras.ubuntu.com when I used the expert mode installer, but I got the above error when doing apt-get update. How do I fix this?
