10.10 - Where can I get "DA360C64005E0276" public key for "ppa.launchpad.net maverick Release"?

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


W: GPG error: http://ppa.launchpad.net 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
keyserver.ubuntu.com --recv-keys
005E0276

and then :

sudo aptitude update or sudo apt-get update again.
