This question already has an answer here:

I cannot upgrade Ubuntu Gnome 16.04.3 to 17.04. I have switched the setting in Software & Updates to Notify me of a new Ubuntu version: For any new version, I also tried editing /etc/update-manager/release-upgrades and verified that Prompt=normal was indeed set.

I run

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

then

sudo do-release-upgrade -d

but it always returns:

sudo do-release-upgrade
Checking for a new Ubuntu release
Upgrades to the development release are only 
available from the latest supported release.

This is not a duplicate of the previous question; the path for Ubuntu GNOME is 16.04.3 to 17.04. There is no 16.10 release of Ubuntu GNOME, so I'm not skipping any release versions.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • You can't upgrade from 16.04 to 17.04, and it is a bad idea to upgrade an LTS to a non-LTS release. It makes no sense. – Pilot6 Aug 16 '17 at 21:00
  • I believe the path aught to be 16.04 --> 16.10 --> 17.04, but note non-lts versions – George Udosen Aug 16 '17 at 21:01
  • 16.10 is EOL, so there is no path. – Pilot6 Aug 16 '17 at 21:01
  • The path is not true for Ubuntu Gnome. You must go 16.04.3 to 17.04. There is no 16.10 release of Ubuntu Gnome. – cmay Aug 16 '17 at 21:10

do sudo update-manager -c in order to update from 16.04 to 17.04

  • This is a wrong answer. – Pilot6 Aug 16 '17 at 21:01
  • no it is not a worng answer I just updated from 16.04 to 17.04 yesterday! – Camden Aug 16 '17 at 21:03
  • Its my pleasure to help you – Camden Aug 16 '17 at 21:08
  • Also worked for me! Updated from 16.04 LTS to 17.04. Thanks – dontbyteme Sep 14 '17 at 12:20
  • You may have to reboot it a few times but it will grab the upgrade in the end. However you are jumping on with a development distribution - so don't do this to your production installs. – jharrell Jan 25 '18 at 21:28
