When I apt-get update I get the following error:

W: GPG error: maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DA360C64005E0276

How to fix this? Where can I find this key to import it?

it's easy you have to download the PPA GPG key :

sudo apt-key adv --keyserver --recv-keys 005E0276

and then :

sudo aptitude update or sudo apt-get update again.
