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?

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.
