How to install openjdk-8-jdk on Debian 10 (Buster)?
Solution 1
Alternatively, you can use adoptopenjdk repository:
wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -
sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/
sudo apt-get update && sudo apt-get install adoptopenjdk-8-hotspot
https://adoptopenjdk.net/installation.html

WARNING: this answer suggest unsupported and dangerous mixing of Debian releases. Follow the advice on your own risk, as it can break the system on upgrades, as explained in http://wiki.debian.org/DontBreakDebian#Don.27t_make_a_FrankenDebian
Package mirror search steps:
-
In the Search package directories search for openjdk-8-jdk. You can see two results:
- stretch (oldstable) (java): OpenJDK Development Kit (JDK)
- sid (unstable) (java): OpenJDK Development Kit (JDK)
-
Choose stretch repository
-
Scroll to the Download openjdk-8-jdk section and choose your architecture. For example amd64
-
Now you can see mirrors list and instructions how to install the package via apt:
You should be able to use any of the listed mirrors by adding a line to your /etc/apt/sources.list like this:
deb http://security.debian.org/debian-security stretch/updates main
Installation steps:
-
Install software source manager
apt-get update apt-get install software-properties-common -
Add mirror with openjdk-8-jdk
apt-add-repository 'deb http://security.debian.org/debian-security stretch/updates main' apt-get update -
Install openjdk 8
apt-get install openjdk-8-jdk
Note: You can use steps above to find an official Debian mirror with any other package you want to install

You can search the Debian packages site and find out the openjdk-8-jdk package for Debian 10 is only available from unstable (sid) repository currently.
At first it is good to check and save current system-wide symbolic links for already installed Java SDK/JRE packages if any:
ls -la /etc/alternatives | grep java > previous-java-alternatives.txt
Then check is this package can be installed with current configuration:
apt-cache policy openjdk-8-jdk
If no then you need to add unstable repository to the sources list.
The negative output may imply that you prefer to use stable repositories and usually it isn't appropriate for you to update all other software from unstable repositories.
So before adding unstable repository to the sources list make sure APT::Default-Release configuration option is set to "stable":
grep -r Default-Release /etc/apt/
If no (as by default) then set it as recommended in that answer by creating this file:
/etc/apt/apt.conf.d/99defaultrelease
APT::Default-Release "stable";
Now you're ready to add the unstable repository to the sources list. Before I prefer to check what mirror was selected by me when system was installed. Just look to main sources list:
cat /etc/apt/sources.list
In my case the output shows that mirror.yandex.ru server is used as system source. So I use the same for unstables and add this file:
/etc/apt/sources.list.d/91-debian-unstable.list
deb http://mirror.yandex.ru/debian/ unstable main
deb-src http://mirror.yandex.ru/debian/ unstable main
(I also have 90-debian-testing.list file for the testing repo.)
Then update package lists:
apt update
And check you system wont update from unstable sources:
apt list --upgradable
And recheck is required package can be installed:
apt-cache policy openjdk-8-jdk
Do install the package:
apt install openjdk-8-jdk
Look at new symbolic links:
ls -la /etc/alternatives | grep java-8
Just waste few seconds on them (or continue with man 1 update-alternatives).

This is my script which I use to install OpenJDK 8 on Bitbucket's Pipelines Docker image NodeJS 10.16.2. But now I see that this docker image is based on Stretch...
It is based on https://github.com/docker-library/openjdk/blob/89851f0abc3a83cfad5248102f379d6a0bd3951a/8-jdk/Dockerfile

I needed to install a 32-bit version but this wasn't available at adoptopenjdk far as I could see. I tracked down a copy of a binary at java.com i their downloads area:
jre-8u241-linux-i586.tar.gz
All I needed was the JRE (rather than a JDK, but the process should be the same for either) and since it was also for a personal use only, the Oracle binary was OK (they have limitations in this regard).
I downloaded the binary and placed it in the home folder (~/) of the user that needed to run it and then unzipped it like so:
mkdir ~/java && cd ~/java && tar -xf jre-8u241-linux-i586.tar.gz
Then added the location to the path of the user that would run the Java application by appending this line to ~/.profile:
export PATH=$PATH:/home/youruserid/java/jre1.8.0_241/bin
This worked fine for my case but there are no doubt better ways to install a binary. For example so it is available for all Unix users rather than just one.

It seems Debian does not support openjdk-8-jdk anymore due to a security issue. What is the easiest way to install openjdk-8-jdk for Debian 10 (Buster)?
