Peter, I've re-done a fresh install of Ubuntu on a USB - still having problems.
1) I did the same steps as before (installing everything from frcsim-installer.sh).
2) I see the permissions on the wpilib directory are still incorrect, so I fix them with chown -R and chgrp -R.
3) I look for the 2016 world in the ~/wpilib/simulation/worlds folder -> I don't see it - should I?
4) I create the robot sample app in Eclipse - and now with your latest change I no longer get the original error message, however, I get the following message from Eclipse:
---------------------------------------------------------

5) Eclipse used to automatically run Gazebo and the Driver Station? So maybe this has changed? I run them both manually, first running "frcsim" from term then "Sim DS" from the menu.
6) I then try running the robot application again from Eclipse and I get a different message as follows:

7) In my terminal where I ran frcsim, I see this message:

Is there something I should try or do you need to take a look at the install script?
