Keyring issue on Raspbian

[RogueIMP]

I was getting a GPG error when trying to add the repository. You may want to add the below instruction prior instead of after, for users who are using Raspbian. It will save some confusion, and time.

sudo apt-get install deb-multimedia-keyring

It's already there in the instructions. It's just that you need an initial apt-get update before apt-get install deb-multimedia-keyring and yes, you'll get a warning.
