install openjdk 21
I have Ubuntu 22.04.3 LTS.
I have run
sudo apt update
but when I execute
apt install openjdk-21
the package can’t be located

E: Unable to locate package openjdk-21
even this package seems to be added in Sept:
https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa
where is the right place to see the last openjdk version added to the ubuntu repository?
when I tab on:
$ sudo apt-get install openjdk-
I get up to java 19:

As of 13-11-2023, the openjdk-21 package for Ubuntu 22.04 is in the -proposed pocket of the Ubuntu repositories.
In other words, it’s still in testing.
If you wish to help test the package, see how to add the Proposed repo. Testers should be experienced with how to troubleshoot problems and file useful bug reports.
If you don’t wish to help test, then simply be patient. The package will migrate to the 22.04 Universe repository when testing is complete.
For newer releases of Ubuntu (like 23.10), the package is already in Universe.
If you add a PPA or other non-Ubuntu version of OpenJDK, remember that it’s likely to be incompatible with the (supported Ubuntu repository) Ubuntu package. So keep track of what you install; you might need to remove all of it.
