  • Can you add the error message? – Eranda Peiris Apr 27 '18 at 3:50
  • Ubuntu by default doesn't upgrade 16.04.x to 18.04, but offers it when 18.04.1 is released (for maximum stability) – guiverc Apr 27 '18 at 4:01
  • sudo do-release-upgrade Checking for a new Ubuntu release No new release found. – Auno Gohe Apr 27 '18 at 4:12
  • It is always better to make new clean install instead of updating. note: save your files and settings from /home directory etc., and even better to have separate partition for /home directory for this case. – Drakonoved Apr 27 '18 at 4:16
  • @guiverc, when is that expected to be ? – Muhammad Gelbana Apr 29 '18 at 21:10

I was having the same problem. But then I run this command in terminal:

update-manager -cd

and I got this:

update notification

Run the above command and see if it solves your problem.

  • The release is already downloadable but I can't get upgrade yet ! – Muhammad Gelbana Apr 29 '18 at 21:10

There is still no information about new release here: http://changelogs.ubuntu.com/meta-release So it will not upgrade
