error launching moveitsetup assistant

edit

On launching move it setup assistant, I get an error message saying that the process has died. I have used

sudo apt-get install ros-indigo-moveit

source /opt/ros/indigo/setup.bash

to install and setup the environment. I have also used sudo apt-get update, unfortunately the error persists
