    Re: error when trying apt-get update?

    Both of you can check for the GPG sig at wherever you have got the ppa from

    insanity99 - your second error Duplicate sources.list - backup and then open the file for editing

    Code:
    sudo cp /etc/apt/sources.list /etc/apt/sources.list.2701
    gksu gedit /etc/apt/sources.list
    You should find the same line in there twice - delete one of them and save, then run

    Code:
    sudo apt-get update

    Re: error when trying apt-get update?

    I thought PPA's couldn't be GPG signed, or at least they couldn't when I last checked. When did this change?

    Yes. I don't know why, but this is a quiet common warning.

    I've found the solution here: http://ubuntuforums.org/showthread.php?p=6616484 (post #2, thanks to taavikko)

    It would be nice to write a little howto for future reference,
    but I'm lazy .
