When i tried to check for updates with the update manager this morning i got this: W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7274A4DAE80D6BF5

It was working perfectly yesterday, anyone know how i can fix this?

Come on someone must know how to solve this, i can't download any updates until this is fixed and it's far from convenient. :sad:
