    If you post the output from the command I gave in post#4 (it's just a matter of using copy and paste) we could see which repositories are missing their gpg keys. I can't really answer your questions until you provide the needed info.

    Re: could not authenticate while installing a package

    There's nothing there about missing keys. How about
    Code:
    sudo apt-key update
