I just started following this digitalocean article and did every step until the do-release-upgrade part.

However I get 

Checking for a new Ubuntu release 
No new release found

I've tried sudo do-release-upgrade as well.

There are 2 ways you can upgrade to 16.04 LTS, using software and update or terminal

Software and update

In software and update window on the 3rd tab you can find the os updates just click install.

Update Ubuntu using software and update

Terminal

Check this article hope that I helps you

For short here are some commads to do upgrade from ubuntu 15.10 wily werewolf to ubuntu 16.04 xenial xerus (LTS), open a new Terminal and type them one by one

sudo apt-get update

sudo apt-get upgrade

sudo apt-get dist-upgrade

at last :

sudo update-manager -d

and click upgrade and continue by choosing upgrade and start upgrade till it starts upgrading

  • This worked! BTW why did I have to install dist-upgrade? – Alex Sep 07 '16 at 12:04
  • My third tab does not look like that screenshot. No luck from either method. – Dronz Sep 15 '16 at 07:01
  • ... Hmm, eventually, after many re-tries fiddling with the updater settings, it seems like changing the upgrade setting from "long-term-support versions" to "all versions" got it to find 16.04, though that doesn't make much sense since 16.04 is LTS, no? – Dronz Sep 15 '16 at 07:09
  • @Alex I'm not sure why you had to install dist-upgrade, check this hope that it helps. – Mehdi Shahamirian Sep 18 '16 at 06:13
  • @Dronz Why no luck? Give more information about what you have. – Mehdi Shahamirian Sep 18 '16 at 06:14
  • @MehdiShahamirian As in my second comment, it seems it was not showing me 16.04 until I set upgrades to "all versions" rather than "long-term-support versions", but that doesn't make sense to me, as I think 16.x is a long-term-support version, so I would expect it to show it to me with that setting. But I believe I only made that one change during the session where it then offered to upgrade to 16.04. Seems like a bug or at least a very confusing UI wording. – Dronz Sep 18 '16 at 15:42
