This question already has an answer here:

The last week of next month ubuntu will most likely release 18.04 LTS. Now my system is 14.04 and next month I want to upgrade it to 18.04. Can I directly upgrade my system from 14.04 to 18.04 or I have to first upgrade from 14.04 to 16.04 and then to 18.04? I really want to avoid the second method of upgrading.

Edit:

How should I update 14.04 to 16.04. I tried this method sudo update-manager -d and installed all the necessary software and restarted the system. Again I run sudo update-manager -d and it showed that my computer is upto date but doesnt have any button to update to 16.04

    You can try, but that way is unsupported, and lots of things changed. – mikewhatever Mar 17 '18 at 11:33
  • but that way is unsupported can you explain of which you are talking about – Eka Mar 17 '18 at 13:32
  • Your edit is really a different question. Please see How do I upgrade to a newer version of Ubuntu? – wjandrea Mar 17 '18 at 16:26
  • The 2 questions reported above speak about old versions (2010,12->14,11->13...) and report really old news. The official page about release notes if LTS 18.04 Bionic Beaver at present say nothing about the "version skipping". Is there any official (2018 updated) answer about a direct upgrade from 14.04 to 18.04? – Hastur Mar 29 '18 at 11:37

No.

Ubuntu does have LTS→LTS upgrades, allowing you to skip intermediate non-LTS releases...
But you can't skip intermediate LTS releases. You have to go via 16.04.

Unless you want to do a fresh install of 18.04 on release.

I should also note that the LTS upgrade pathways are usually only available some time after the main release. So don't expect to be able to upgrade from 16.04 on the day of 18.04's release.

    So I should upgrade it first to 16.04 can you also include the code for that. – Eka Mar 17 '18 at 13:30

  • @Oli. Hi, you said "But you can't skip intermediate LTS releases". Is it a strict policy, is it only the past experience or did you read about it on some official ubuntu documentation? – Hastur Mar 29 '18 at 11:33
  • Here: wiki.ubuntu.com/BionicBeaver/ReleaseNotes , it says that upgrade will be available at end of july. – kebs Jun 2 '18 at 16:24
