    Wink Fixing: WARNING: The following packages cannot be authenticated!

    When you upgrade to a new version of Ubuntu/Debian, then you may see the following message:
    Code:
    WARNING: The following packages cannot be authenticated!
      foo bar
    Searching google doesn't turn up good hits for fixing this, so i provide here the solution to this problem, which is really simple:
    Code:
    sudo apt-get remove debian-keyring debian-archive-keyring
    sudo apt-get clean
    sudo apt-get update
    sudo apt-get -y install debian-keyring debian-archive-keyring
    In a world without walls and fences, who needs Windows and Gates?
    Linux is like a wigwam.... no Gates, no Windows but Apache inside!

    Thumbs up.

    I've seen a lot of "ack-grep update" recommendations, which of course don't solve this problem

    Your advice hands-down fixes it.

    Someone should make this a sticky somewhere!

    I encountered the following error for packages that have previously had no problems,
    Code:

    The fix given by WitchCraft worked perfectly.
