Hello Umer, I believe this is working as intended.
By default Ubuntu users in the admin or sudo group have full privileges
on the system via sudo.
If you can reproduce this without being in either of these groups,
please re-open, attach your sudoers(5) file, and a terminal transcript
showing id(1) output and the problem.
** Package changed: unity (Ubuntu) => sudo (Ubuntu)
