Comment 0 for bug 1630176

https://help.ubuntu.com/community/CheckingYourUbuntuVersion describes two ways of getting your current Ubuntu version: via system settings, and via terminal. For me, those two methods give me a different version (14.04 vs 16.04). I upgraded my pre-installed trusty to xenial, so the version printed on terminal is correct. That means that the system settings displays the wrong version. See attached screenshot.
