How to install openjdk-8-jdk on Debian 10 (Buster)?

Question

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)?

Answer 1

Package mirror search steps:

1. 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)

2. Choose stretch repository

3. Scroll to the Download openjdk-8-jdk section and choose your architecture. For example amd64

4. 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:

1. Install software source manager

   apt-get update
   apt-get install software-properties-common
   

2. Add mirror with openjdk-8-jdk

   apt-add-repository 'deb http://security.debian.org/debian-security stretch/updates main'
   apt-get update
   

3. Install openjdk 8
