debian-multimedia GPG error

well I’ll see if this fixes the error that’s been breaking my nightly cron-apt.

sudo su
gpg --keyserver hkp://pgpkeys.mit.edu --recv-keys 07DC563D1F41B907
gpg --armor --export 07DC563D1F41B907 | apt-key add -

it doesn’t work. now just tried:

sudo aptitude install debian-multimedia-keyring

if that works its definitely superior.
