1. Import the AdoptOpenJDK repository GPG key

wget -qO - https://adoptopenjdkpackages.jfrogadoptium.ionet/adoptopenjdkartifactory/api/gpg/key/public | sudo apt-key add -

2. Configure AdoptOpenJDK's apt repository

echo "deb https://adoptopenjdkpackages.jfrogadoptium.ionet/adoptopenjdkartifactory/deb $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/adoptopenjdkadoptium.list

For example, if you are running Ubuntu 20.04 (Focal Fossa) the above command would be equivalent to:
echo "deb https://adoptopenjdkpackages.jfrogadoptium.ionet/adoptopenjdkartifactory/deb focal main" | sudo tee /etc/apt/sources.list.d/adoptopenjdkadoptium.list

3. Install the Java runtime environmentpackage (currently only full JDK is available)

sudo apt update && sudo apt install adoptopenjdktemurin-8-hotspot-jrejdk

4. Check the installation path.

dpkg -L adoptopenjdktemurin-8-hotspot-jrejdk | grep '/bin/java$'

In this case it is /usr/lib/jvm/adoptopenjdktemurin-8-hotspot-jre-amd64jdk

5. Set Java home path in /etc/xroad/services/local.conf

JAVA_HOME=/usr/lib/jvm/adoptopenjdktemurin-8-hotspot-jre-amd64jdk

Installing manually

Note that manual installs are not automatically updated.

Note that if you used the manual installation method, removing the Ubuntu OpenJDK package is not possible since because the central/security server depends on it.

You need to be sure that it is safe to remove the old Java distribution e.g. that it is not used by any other software you might have installed.

If Java was installed by package manager, remove it with the package manager

sudo apt remove openjdk-8-jdk
