"Key" issues

[Beloved Bob]

When I try to update I get the following error...

W: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7D2C7A23BF810CD5

Can someone tell me what is happening? Is it important? What do I need to do, if anything?

Thanks!
