I am currently using 18.04 LTS in the web server production environment. I was under the impression that Ubuntu 20.04 LTS was ready to go, since it was released in april 2020.

But running do-release-upgrade tells me "There is no development version of an LTS available".

Does this mean that 20.04 LTS is not ready yet?

  • LTS users usually want stability, so the upgrade doesn't occur until AFTER the first point release (which is likely in hours). Even after 20.04.1 has been released (which is actually the date/time for the ISO release for new installs), it's a number of days before the taps get turned allowing the prior LTS release to detect and offer upgrade; which ensures stability. – guiverc Aug 06 '20 at 12:38
  • This should not have been closed as a duplicate simply because some answers match, it is a bad message. Why would anyone upgrade to a development version anyway? By definition it is a risk? – mckenzm May 16 '22 at 19:12

According to the Focal Fossa (20.04.1 LTS) Point-Release Status Tracking page, upgrades are not enabled yet due to "a few upgrade blockers".

This issue was reported as bug #1890936.

Upgrade from 18.04 is done with 20.04.1 (note the .1).

That point release is set for release on august 6th 2020. So you need to wait a little bit longer as it is not the 6th all over the world yet.

It was initially set for July 23rd but that got postponed to Aug 6th.

  • Thank you, that makes sense – Jette Aug 06 '20 at 12:33

    I'm running 20.04, and it already updated to 20.04.1 more than a week ago. So I'm guessing august 6th is the day where it's possible to update from earlier versions to 20.04.1 – Artur Meinild Aug 06 '20 at 12:34

    Yes we 20.04 users got it on the 23rd of July :) Added that just before you made the comment :+) – Rinzwind Aug 06 '20 at 12:36
  • That also explains why I couldn't find a reliable source on the date, since some said July 23 and others August 6 - turns out both were correct. ;-) – Artur Meinild Aug 06 '20 at 12:38

    @ArturMeinild the date refers to the release of the ISO, which yes is after installed users get the upgrades. As it stands right now, I see only one product that hasn't clicked ready for upgrade, but that'll happen... Upgrades from prior releases though occur after that date, a decision which is made & change to a file made when the deemed appropriate. The date is ISO release only. – guiverc Aug 06 '20 at 12:42

    Well, as of today (7th August in the UK) My 18.04.4 system is still not seeing the 20.04.1 LTS upgrdae as being available. do-release-upgrade returns the message There is no development version of an LTS available so I'm upgrading with do-release-upgrade -d which says its upgrading to 20.04. – Fat Monk Aug 07 '20 at 10:22

    After updating with sudo do-release-upgrade -d I can confirm I am now running 20.04.1 LTS. – Fat Monk Aug 07 '20 at 10:52

    @FatMonk what exactly do I get when I add the '-d' option? The "d" is for "development" right? Does this mean that I get a release not ready for production? – Jette Aug 10 '20 at 09:07

    @Jette it seems not. It looks like the full release version 20.04.1. I had exactly the same concern as you because the docs describe -d as grabbing a dev release, but in this case as there 8s no Dev release available it grabbed the latest LTS version which I was not being offered by Software Updater. – Fat Monk Aug 10 '20 at 10:10

    @Jette no. Thing is ... at some point the development release equals the regular release. You can still use the -d but effectively it would be the same as downloading the current regular ISO and install that. – Rinzwind Aug 10 '20 at 10:18
  • @Rinzwind I am currently upgrading 3 production webservers from 16.04 to 18.04. I am wondering if it is safe to proceed to 20.04 (while I'm at it)... or should I wait until I can do do-release-upgrade without the -d option? – Jette Aug 10 '20 at 12:37
  • Hmmm. If that is the case I (but I am not the-know-it-all ;) ) believe you are doing it wrong ;-) Going to a new LTS ... I would do that on a new system and not with an upgrade. 16.04 on system 1. 18.04 on system2. Works? Replace 16.04 with 20.04. Restore user data from 18.04 to 20.04. If you only can do this on 1 system: go 16->18 then make sure it works and a couple of weeks later do 18->20. Never make upgrades more complex than needed :) – Rinzwind Aug 10 '20 at 14:19

    and now it is the 12th of august, and still "There is no development version of an LTS available." When precisely is it expected to become available? – Rhialto supports Monica Aug 12 '20 at 16:52

    Aug 13, on Ubuntu 18.04.5 LTS. Without -d, I still get "There is no development version of an LTS available". Do you guys know where to find some more info on the general availability? – rdesgroppes Aug 13 '20 at 10:16

    So it's 14th, more than a week later and still "There is no development version of an LTS available." both from do-release-upgrade and software updater. So I tempted to downvote this answer as completely incorrect unless some information w.r.t. delay is added (i.e. if there is some critical bug delaying the roll out or something else). – Dan M.

    And now it's the 29th and it's still not yet ready. :\ – James T Snell Aug 29 '20 at 16:42

    Now we're well into September and it still won't do the update. – OrangeDog Sep 07 '20 at 10:34
