Ubuntu PPA Keyring signature issue
GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2524246B1CC723DB
The clue here is the last string of characters, which is the public key. In order to add the key for this particular PPA (or repository), issue the command:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys KEY_ID
Where KEY_ID is the last string of characters in the error (in this case 2524246B1CC723DB).
