    Re: Updating repo problem

    Those errors are often related to your gpg key. When you enabled those repos did you also have a gpg key that you were suppose to import?
    There's a guide to doing that here. Sorry that's a redhat guide but it's a similar process. I'll include the ubuntu one if I get a chance.
    Good site to search for guides & how-tos.

    Go to Applications > Accessories > Terminal, execute these commands:
    Code:
    wget http://archive.ubuntu.com/ubuntu/project/ubuntu-archive-keyring.gpg -O- | sudo apt-key add -
    sudo apt-key update
    sudo apt-key net-update
    Now it should be ok:
    Code:
    sudo apt-get update
