deb-src http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu intrepid main

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 247510BE
sudo apt-get update

W: GPG error: http://ppa.launchpad.net intrepid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9BDB3D89CE49EC21

W: You may want to run apt-get update to correct these problems

Fix:
Enter this command, replacing 247D1CFF with your NO_PUBKEY-key last eight digits from the error-message to import the key:
gpg --keyserver keyserver.ubuntu.com --recv CE49EC21

Then add the key to your software sources, again, replace 247d1cff with the keynumber used in above command:
gpg --export --armor CE49EC21 | sudo apt-key add -
