I've verified that "Notify me of new Ubuntu version" is set to "For long-term support versions" in Software & Updates. Yet when I run do-release-upgrade I get "No new release found." Please help.

Command do-release-upgrade -c -d at this moment will get 16.04 LTS

  • What's the -c option? It isn't listed in http://manpages.ubuntu.com/manpages/trusty/en/man8/do-release-upgrade.8.html – muru Apr 22 '16 at 23:58

    @DavidFoerster Excuse me, do you know why do-release-upgrade without -d says “No new release found”? Is it a devel release? – Daniyal Javani Apr 23 '16 at 13:56
  • @Daniyal: This (the comment section of an answer) is not the right place to ask a different question. Please ask a new question instead. – David Foerster Apr 23 '16 at 16:11

    It looks like -c is a check option to just print the release that would be taken. No instell will happen with that option set but it is very useful to see what you would get. The -d option tells the command to look for development releases too (and if you are on LTS that means development LTS ones only). Could you update this answer to highlight those points and make it clean that a second command will be need to install what is presented at the prompt? – TafT Jun 08 '16 at 08:56
  • @muru the -c or --check-dist-upgrade-only option is to "Check only if a new distribution release is available and report the result via the exit code." It and other options can be viewed by issuing do-release-upgrade -h – kzh Jul 27 '16 at 12:37

Usually, LTS upgrades are not supported in the initial LTS-next. That is, 12.04LTS could not be upgraded to 14.04LTS, but only when 14.04.1LTS was released. I would expect the same to be true this time, and that you'll have to wait until 16.04.1 to be released. I don't know the planned release date, but it's usually about three months after the main release.

You will be notified when it's ready to be upgraded and you should not try to do it manually by entering commands unless you really know what you're doing. Upgrading LTS to LTS is more difficult than normal upgrades and for most people, it's more important, so this needs more time to be handled correctly.

The ".1"-releases are Ubuntus version of "Service packs". So in other words, wait until the first SP is released. I would guess it'll happen sometime in July.

As of 9th May this still does not work

sudo do-release-upgrade

But it worked for me with -d flag.

sudo do-release-upgrade -d

The 16.04 LTS Final Release is not out for upgrade yet but it will be released sometime later today/tomorrow.

To have a check you can simply do from terminal 

do-release-upgrade -c

this will check if the actual release is open. If yes run the command

sudo do-release-upgrade

without any parameter.

The LTS versions only upgrade to LTS by default. Which the new LTS has not hit the mirrors yet.

Strangely I got 16.04 Ubuntu Mate for Raspberry Pi yesterday.

  • The raspberry pi version is maintained by a different team, they probably just did it early –  Apr 21 '16 at 14:13
