I heard that April 26 will be the day Ubuntu 18.04 is going to be releasing its stable version.

Is it possible to know in advance at what time?

    We are busy testing (and if necessary, the developers are squashing some remaining bugs). Please wait for some more hours (or days if a new showstopping bug appears) . Ubuntu Development version / How to participate – sudodus Apr 26 '18 at 6:03

    Why does it matter? The daily-live is up to date and usable. Might be some bugs here and there but that does not mean those will affect you. I am on 18.04 and have been for a month already. – Rinzwind Apr 26 '18 at 8:47

    When it is ready? Soon™! Or in other words when its there it is there, same question we get every time a new release is coming and the same answers apply here too. – Videonauth Apr 26 '18 at 8:56

    This question is important in that I need to stop clicking 18.04 bugs as off-topic due to being in development phase. – WinEunuuchs2Unix Apr 26 '18 at 10:30

    IMHO I disagree with the duplicate mark for this question. Here it is asked if it is possible to know in advance WHEN (time in the day) it will be released and not where to see if it is already released... Users 3k+ can you vote for reopening? [@Rinzwind maybe you can rethink your vote... I even fixed the misaligned headers :-) ] – Hastur Apr 26 '18 at 12:51

Each time it is different :-)... and unknown in advance (at least until the 18.04).

Update: (Thu Apr 26 22:59:59 UTC 2018)
Now it's out. You can start from the Bionic Beaver page or from the links below.

One of the most comfortable solution to know when a new release exits, is to subscribe to the ubuntu-announce mailing list and wait for a mail. (As you can check there are not so many and it will not spam your account).

It will appear in the Bionic Beaver (18.04) page instead of the beta-2 version, or in the download sections of the Ubuntu site [d1, d2], or on the cdimage Ubuntu site in the release directory (again not the beta-2)...

Nonetheless you may have some hints from the past [12.04, 14.04, 16.04],
looking for the 1st and last ISO file creation time present in the old-releases Ubuntu site:

 Release  Day      1st ISO file       Last ISO file          Last FILE        
12.04 LTS 26th '12 Apr 23 12:27 '12 Apr 25 16:13 2012-04-26 09:51
14.04 LTS 17th '14 Apr 16 21:13 '14 Apr 17 01:37 2014-04-17 15:00
16.04 LTS 21st '16 Apr 20 22:30 '16 Apr 20 23:38 2016-04-21 11:08

Of course you have to search for the first release (the one without .1, .2, ...).

For a somehow more "trusted" version (suggested as automatic update from the previous LTS) you should usually wait until the .1 release (usually in July-August; this time it is scheduled for July 26.

We should mind the timezone and that we should even wait until the files are uploaded to the various mirrors.


According to this, this is a bug that delayed the release of Ubuntu momentarily.

About seven hours ago, the development team found a bug and it’s currently being fixed. Apparently, Bug #1767067 affects the live session options in Ubuntu, Ubuntu Kylin, Ubuntu Budgie, and Ubuntu MATE flavors. As per the latest update, the team is working hard to fix the bug and testing the release. (Update: The team has fixed the bug and the official release will be out anytime soon).
