Checking for a new Ubuntu release No new release found.

Checking for a new Ubuntu release There is no development version of an LTS available. To upgrade to the latest non-LTS development release set Prompt=normal in /etc/update-manager/release-upgrades.

    @AlokKumar 24.04 is not released yet. The Daily Build is designed for people who want to test the next version of Ubuntu during its development. 24.04 has a release schedule that has its timeline for release being in late April. Until that happens and it is announced officially as "released", you will not see it in do-release-upgrade nor will it be supported on this site until it is released. – Thomas Ward Mar 08 '24 at 19:44
  • Read man do-release-upgrade and serach for --devel-release option, ie. you want to go to the development release which is what it is for. You can also use the -d as a shorter option, OR follow the documented upgrade procedures which list it too. – guiverc Mar 11 '24 at 07:15
  • Ubuntu 24.04 (noble) doesn't yet exist; it's currently the development release Ubuntu noble and remains that until it reaches RC state which isn't expected until after 18 April 2024, and isn't on-topic here until release on 25 April 2024. https://discourse.ubuntu.com/t/noble-numbat-release-schedule/35649 Please refer https://askubuntu.com/help/on-topic. For support issues with Ubuntu noble you'll need to use a #ubuntu-next or #ubuntu+1 site (IRC, UF etc) – guiverc Mar 11 '24 at 07:15
  • I wrote an answer on this only recently (on a rather similar question)... I also close-voted that question (thus that question may have been deleted) as the development release is off-topic until it's released.. As in that answer; the --devel-release or -d action causes the normal released meta file (https://changelogs.ubuntu.com/meta-release) to not be used; insteading using the development version (https://changelogs.ubuntu.com/meta-release-development) to be used instead where noble can be found... Exactly as its documented – guiverc Mar 11 '24 at 07:20
  • FYI: I note you mention daily in a comment; refer to https://iso.qa.ubuntu.com/ for probably the best place to find what daily ISOs are available; ie the ISO Quality Assurance tracker. It lists all dailes & points to where they can be downloaded at https://cdimage.ubuntu.com/ (which includes non-released ISOs too) including for re-spins (ie. what will be 22.04.5 etc for already release products). I suggest using a #ubuntu-next or #ubuntu+1 site for help though with unreleased or QA intended products. – guiverc Mar 11 '24 at 07:23

    Does this answer your question? How do I upgrade to the development release (aka. Ubuntu+1)? – muru Mar 11 '24 at 07:41

The output is correct. 23.10 is the most recent release of Ubuntu. There is no newer release yet.

About 48 days from today, Ubuntu 24.04 is planned to be released. It is NOT released yet. Until then, it is in development.

24.04 = yy.mm
yy = 24 (2024)
mm = 04 (April)

    It's the daily snapshot of current development that will become 24.04 upon release. It is intended for testing. Development and testing of software takes place in the open, of course. We want more testers! Please do test it, and report the problems you discover to the bug tracker. – user535733 Mar 08 '24 at 17:56

    Reminder: AskUbuntu is not a venue to discuss testing or pre-release development. AskUbuntu is for support after release. – user535733 Mar 08 '24 at 17:58

  • @ArturMeinild Sorry, I didn't know that, so I ended up with a couple of development 24.04 machines. Sarcasm off: it just work, see man do-release-upgrade about -d switch. – Maxime Mar 12 '24 at 11:06
