My kid really wants me to upgrade the minecraft server I run from 1.17.1 to 1.18, but when I tried, I found that it required Java 18. It looks like Java 18 is only available on the latest release of Ubuntu, but I want to stick with the LTS releases. Is there a backport available for Java 18?

    Oops. It needs Java 17, not Java 18. And, I learned from a similar question posted here that installing Java 17 is simply `sudo apt install openjdk-17-jre` – jrennie Dec 04 '21 at 14:43
  • Anyway, Java 18 would be released in March 2022. So you need to wait till March :) – Kulfy Dec 04 '21 at 14:49

Since Java Edition 1.17(21w19a), Minecraft requires Java 16 or newer. In Ubuntu 20.04 you can meet this requirement by installing openjdk-17-jre as follows:

sudo apt update
sudo apt install openjdk-17-jre
