    It takes until after the first point release (22.04.1) for do-release-upgrade to become available for general use. This is usually in August.

    Some years, when there have been known problems, the team has held back the availability of an update through do-release-upgrade for a long time, until the issues are ironed out. This can be particularly so if you're on the LTS-to-LTS track.

  2. There are currently some issues with upgrading from 21.10 to 22.04. That is why do-release-upgrade is showing jammy as a development release. If you want to take the risk and go ahead with the installation use the -d switch, but I would recommend waiting until the issues are solved.

    The release date is the date when the iso is available for download. Upgrades from non-LTS releases may take a few more days and for LTS to LTS upgrades, Ubuntu releases the upgrade after the first point release (22.04.1) three months after release.

    I've seen people reporting upgrading from 21.10 and end up with the system not booting, so it's better to be patient…

  3. I got the same message 'This release is still in development.' but was also prompted to continue. I said "y"and my machine is currently upgrading.

  4. I'm not a Linux expert, however, you should use do-release-upgrade without the -d flag. -d flag is for the development version.

    I did the same and it's currently upgrading!
