    And what are you doing? What command did you run? What did you try to solve it? Obviously you searched Google for the error before coming here, so what did that tell you? Please edit your question and explain what you were doing and what you've tried. – terdon Jul 28 '17 at 13:32
  • apt has very bad error messages. Has not Release file could also mean you do have a typo in your address or no internet connection at all. You should check if ppa.launchpad.net/gnome-terminator/ppa/ubuntu displays the files in a browser. – CatMan Jul 28 '17 at 13:33

    for me it was 'bionic' and I changed to xenial, fixed the issue, but I don't understand why it doesn't have the bionic dist? – sangress Jan 20 '19 at 15:24

    @sangress If you look at http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu/dists/ you'll see that there's not a bionic distribution directory for this software. – heynnema Jan 20 '19 at 15:28
  • @sangress it was the exact same for me. – marcogmonteiro Mar 9 '19 at 19:13

    Just test it with Ubuntu 20.04 focal fossa and it worked flawlessly. – Reginaldo Santos Sep 3 '20 at 13:29
