I see this Call for Beta Testing Ubuntu 21.04 and Ubuntu Flavours message and I would like to test this version on my sandbox Linux Desktop (I have another Laptop for work tasks).

I see this old AskUbuntu question How to upgrade to a beta version but as I mentionned here « Software & Updates dialog box doesn't contain "Pre-released updates" option any more »

Question: what is the mainstream process to upgrade Ubuntu from 20.10 to 21.04 beta?

    Next to that: it got closed due to https://askubuntu.com/questions/12909/how-do-i-upgrade-to-the-development-release-aka-ubuntu1 Your question is still a duplicate against that one We do not need a topic like this for every release. if you have a new method please answer the topic in this comment – Rinzwind Apr 04 '21 at 08:48
  • Refer https://askubuntu.com/help/on-topic where you'll notice only supported releases of Ubuntu and flavors are on-topic for this site. For hirsute hippo [21.04] questions you'll need to use a development support site such as IRC (#ubuntu+1) or Ubuntu Forums, or wait until after release for this site (expected release date for Ubuntu 21.04 is 22 April 2021 (https://discourse.ubuntu.com/t/hirsute-hippo-release-schedule/18539) when your question will be on-topic here). – guiverc Apr 04 '21 at 11:12

I think maybe the good methods are:

  • via GUI: Alt+F2 and type update-manager -d
  • via command line: sudo do-release-upgrade -d

For this two methods, it is -d, --devel-release option which means update to development version.
