  • Are you trying to perform this installation on a remote server or locally? Commented Oct 27, 2017 at 19:43
  • On local server. Commented Oct 27, 2017 at 19:46
  • You are sending the DISPLAY back to itself. You either need to forward your display to an x11 client, or run a desktop on the server so it has an x11 client Commented Oct 27, 2017 at 20:05
