Adding a Launchpad PPA's key to Ubuntu

Each Launchpad Personal Package Archive (PPA) has its own key that is used to sign the packages.

This screencast shows you a very easy way to add a PPA's key to your Ubuntu system so that you can install the packages from that PPA.

Note: you must make sure you trust the PPA owner to build good software before you install any packages from that PPA.

For newbies like myself to Ubuntu this tutorial will help me reinforce the idea that obtaining the PPA key from third party developers who are launchpad members is extremely important. Instead of me fishing around in no mans land looking for authentications sources for untested software packages! Good job Matt!

without the spaces

Thanks for this tutorial, but I get an error message for package I can't find in the other sources tab:

W: GPG error: ppa . launchpad . net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F44462BDF141B61E

Anybody who can help me?

Really Linux thinking backwards. They are geekish, making thngs unnecessarily complex. PPA, PGP, are we in the military? make things simple, I still dont know what the hell PPA is and why I can't update my ubuntu system anymore.

Thank you. Was looking to set up a Vala in CrunchBang and all of the instructions I found from google seemed outdated and hackish. This is strait-forward and works.
