    apt-get authentication failing

    I only just started experiencing this problem today....

    I was trying to do a normal software update:
    Code:
    sudo apt-get update
sudo apt-get dist-upgrade
    when I ran dist-upgrade, this happened:
    Code:
    WARNING: The following packages cannot be authenticated!
    I've never seen this error before. I googled it and one of the suggestions I found was to reinstall "ubuntu-archive-keyring", but the instructions said you have to do that using aptitude, which I didn't have installed. When I tried to install it (with apt-get), I got the authentication warning again. It looks like I can't install ANY packages without getting that warning.

    as an aside, lately I've been getting a lot of "failed to fetch..." errors when I do updates and I'm not sure why. I assumed it was just packages getting broken during the update process as sometimes happens, but there are no problems on my VPS...so I have no idea. It probably isn't relevant to this other problem anyway.

        Try running:
        Code:
        sudo apt-key update
        Then:
        Code:
        sudo apt-get update && sudo apt-get update
        Windows no longer obstructs my view.

          oops, I forgot to mention I'd already tried apt-key update without any success :\
          also, this is probably unrelated as it's been happening for weeks but it's another problem I need to solve:

            You are in New Zealand? Try switching to another download server.

              no, I'm in Australia...I was assuming NZ was just the closest server there was but I really have no clue!
              can you explain to me how to change the download server?

                Launch Muon Package Manager. Click on Settings > Configure Software Sources. Type your password and press Enter. On the first tab, click the large button to the right of Download from: and click Other... and select a different server.

                  ok, I did that and I have no idea why it was set to the NZ server cause there is indeed one for Australia.
                  however, this is what happened (presumably Muon's way of describing the same thing that was happening with apt-get earlier):

                  p.s. good news: the authentication problem seems to have vanished!

                    Those are PPA repositories, and there is no guarantee that a selected download server will know about them.

                      PPAs do not have mirrors like the normal Ubuntu repos.
                      This last error could also likely be that you have a ppa that does not have a Trusty (14.04) component .


                      And my thought is correct:

                      Going to the ppa's page, it most definitely does not have packages for anything newer than Precise 12.04, so you can remove it.
                      This is one reason why the official upgrader disables PPA entries before proceeding with its job.
