I have set the "Software and Updates" app set to inform me of new LTS releases of the OS (ubuntu Studio 16.04 installed). 16.10 has been out for a while now, but I do not remember getting a notification. I know for sure that I did not upgrade to 16.10 unless it happened without my knowing. I checked the version in the Linux terminal and it reports 16.04, so I tried `sudo apt-get dist-upgrade`, but it returned: `0 upgraded, 0 newly installed`...

Either I am running 16.10 and the version is reported wrong (in the Linux terminal) or I am still running 16.04 and something else is wrong, but which one is it?

As for this being a possible duplicate on how to upgrade: I need to know if I am being shown the wrong OS version, or already upgraded first. I already had an answer on "How to upgrade" which did not work.
