July 15, 2024 -

EDIT: I've ended up installing Microsoft's OpenJDK 21. Had a nice instructions to setup and i didnt need to mess up my debian repositories to get the thing (only add MS one). Sorry die-hard Linux fans

I'm trying to install the JRE of Java 21 in my Debian 12 headless machine, for Minecraft server purposes.

Unfortunately i saw that the packages of 21 aren't available in stable repositories, only on sid (unstable). I don't want to add the whole sid repository to avoid instability and since the only package i want is this one.

So, is there any way to install Java 21 using either apt or a .deb file - without resorting to unpack a .tar.gz? Should i download the .deb on the website and try to install it via gdebi-core? I read that this isn't an advised thing to do due to dependencies and such...

How to Install Java on Debian 12 (Bookworm)

August 4, 2023 - If you get a message like the one shown above, “java: command not found,” your system has not yet added support for Java, so let’s proceed with its installation. For clarity, we shall state right away that Debian provides the “default-jdk” meta-package, a regularly updated one to ship the latest version of the current OpenJDK LTS release for the convenience of its users. So, using the APT command below will install OpenJDK 17 LTS on your Debian 12 (Bookworm) system.

How can I install Java 8 on Debian 12 (bookworm)? - Unix & Linux Stack Exchange

Top answer

Thorsten Glaser, the current maintainer of OpenJDK 8 in Debian, provides a repository which includes OpenJDK 8, built using the Debian OpenJDK 8 package (see also Debian bug #989736).

To install it on Debian 12, download the appropriate repository configuration file:

wget http://www.mirbsd.org/~tg/Debs/sources.txt/wtf-bookworm.sources
sudo mkdir -p /etc/apt/sources.list.d
sudo mv wtf-bookworm.sources /etc/apt/sources.list.d/
sudo apt update

You’ll then see openjdk-8-jdk, openjdk-8-jre, etc. available for installation as usual:

sudo apt install openjdk-8-jdk

I am using the distrubution offered by adoptium, called temurin-8-jdk

mkdir -p /etc/apt/keyrings

wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | tee /etc/apt/keyrings/adoptium.asc

echo "deb [signed-by=/etc/apt/keyrings/adoptium.asc] https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | tee /etc/apt/sources.list.d/adoptium.list

apt update 

apt install temurin-8-jdk

Optional to switch from an old repository
