Adding missing GPG public key to Synaptic

Apparently in some odd cases Ubuntu doesn't automatically get all needed GPG public keys during the system upgrade. I just came across with this issue after upgrading one 64bit HP laptop from Ubuntu 10.04 to 10.10. (not a clean install, but upgrade thru Update Manager) After the upgrade Synaptic update stopped working with the following error about missing public key:

GPG error: maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3AXXXXXXXX"

Not to panic! The fix for the problem is quick and easy! One just has to add that missing key with the below command:

sudo apt-key adv --keyserver --recv-keys XXXXXXXX

Just pick the last eight digits from the error message to the end of the fix command.
