Title:
  hostname is not set correctly by unity-control-center

Status in gnome-control-center package in Ubuntu:

Status in unity-control-center package in Ubuntu:

Bug description:
  Ubuntu 15.04, Linux 3.19.0-22-generic, Unity.

  I used System unity-control-center --> Details to change my computer's
  hostname. This resulted in a state where

  /etc/hostname

  was updated, but the relevant entry in /etc/hosts i.e.

  127.0.1.1       <old-hostname>

  was not.

  Restarting the machine does not update the line in /etc/hosts.

  I believe this is a bug, it cannot be the intended outcome of unity-
  control-center, because it results in a broken state where the
  computer's own hostname is not a know host for itself, in turn
  resulting in many issues with internet applications.
