so i just installed ubuntu today. i've never used any linux system before. i'm trying to install banshee and i ran into this problem when i tried to add the apt line (deb http://ppa.launchpad.net/banshee-team/ppa/ubuntu intrepid main) to the Third Party tab:

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 4874D3686E80C6B7

You have to add the Open GPG key to Software sources.

Here is an extract from a link on that PPA explaining how to do it:

Step 1: Visit the PPA's overview page in Launchpad. Let's go back to the AWN Testing team's PPA (https://launchpad.net/%7Eawn-testing/+archive) that we were looking at earlier.
Step 2: Click the key fingerprint on the overview page. It'll look something like this: B0BE17C2A0C914F086B7B8327D2C7A23BF810CD5`.
Step 3: This will take you to the key's page in the Ubuntu keyserver. Click the ID, which looks something like this: BF810CD5
Step 4: Copy the public key, which will be something like: -- i.e. the portion starting:

Version: SKS 1.0.10

-----END PGP PUBLIC KEY BLOCK-----Step 5: Paste the public key into a text editor and save it.
Step 6: Open System->Administration->Software Sources and click the Authentication tab.
Step 7: Click Import Key File, select the key you saved earlier and you're done! If you go back to that web page and look just below the box with the "deb" info, you'll see a link to the OpenPGP key. Follow the above steps and you will be able to download from that repository.

I hope this helps...

You will find on the page you linked to in the apt sources.list entries section details of how to add the key to your system.

In a terminal

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 6E80C6B7
sudo apt-get update

After the apt update you should have no error.

Any time that you use a ppa you will need to do the same thing again.
