Getting error while install openjdk-15-jdk on my Ubuntu 20.04.1 LTS

Command I'm using: sudo apt-get install openjdk-15-jdk Error: E: Unable to locate package openjdk-15-jdk

I used similar command to install openjdk-14, which ran successfully. What's causing this issue? How can I install jdk-15?

No recommendation for it. sudo apt-get install openjdk-

  • I saw this post, but I am skeptical about it as it's not official. If other versions like 11 13 & 14 are available, why not 15?

  • openjdk-15 is not in the Ubuntu 20.04 repositories (nor earlier releases) simply because the software is too new. The software was not released, packaged into Debian, tested, and debugged before the 20.04 merge window closed. Ubuntu does NOT make major changes to software versions after a release -- that would defeat the main intent of an LTS release, which is that the software does not change during the life of the release. Openjdk-15 is in newer releases of Ubuntu, like 20.10 and the future 21.04.

Ups better you use "apt search openjdk" for the correct command, the first is bad code :P

More recent JDKs are available via snap, Ubuntu's alternative installation approach. Search there, or try:

snap search openjdk

E.g. currently jdk 18 is available.

Note that these versions by default have carefully restricted permissions. See the documentation at jgneff/openjdk: Current JDK release and early-access builds for details and options.

[17-08-2022] thank to @nobody (see comment to the question)

For all older version use this link:

https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt update

and select your version:

sudo apt install openjdk-15-jdk
