    I was having a similar error message as sabdullahi and I tried the commands you posted, fantab.

    It seems to cleared up most of it, but I still get this:

    Try this in Terminal:

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A9E15C2F2B944FEE
    Replace error key (one in bold face) in the above command with one you are having problems with.

    Hope this helps.
