After following a suggestion in the comment to remove compiz I lost my launcher. Now the question is kept on hold asking to upgrade ubuntu. Now my question is does upgrading my Ubuntu to 15.04 and then to 15.10 and there to 16.04 LTS help me in getting back my launcher ?
Also please help me on upgrade path as I would like to update using DVD because online update if in case of internet and power outage could cause permanent loss of data. Please suggest on upgrade path and method.
