Ubuntu: 2 different versions after upgrade


Upgraded from 14.04 to 16.04 on dell xps 13 Core i5. uname shows 4.4.0-22-generic and lsb_release shows 16.04 but when I go to the settings/details, I still see 14.04.

Can someone please assist with figuring it out?


How about your repositories, listed in /etc/apt/sources.list ?

For example, in this line:

deb http://br.archive.ubuntu.com/ubuntu/ xenial main restricted

After the repository address, it's written Xenial(16.04) or Trusty(14.04)?
