Strange apt-get gpg key error

[brightJoker]

Sometime last week, not exactly sure when, but my apt-get update started producing this message:


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 0E931CE221789C97
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 C71839136CF5CE97
W: You may want to run apt-get update to correct these problems
brightjoker@brightjoker-laptop:~$

I know I have to install keyring, but not sure which one. Any help is appreciated as always :)

Download launchpad-update-final.zip from: http://ubuntuforums.org/showpost.php?p=6638010&postcount=42

Extract it in your home directory and run it:

sudo ~/launchpad-update intrepid
then:

sudo apt-get update

Thank you working like a charm now :)

Edit: Random other question though about my Third Party sources, in the gui Software Sources, do I need to have both the repos selected with and without "(source)" at the end or just one or the other?
