MTG-Java 17 Migration
Introduction
This page will walk you through the migration process from the previously used MTG Java 17 package to the Adoptium Temurin JRE 17 package.
| It is always advisable to create a backup prior to implementing any changes. |
Stopping MTG Applications
First, it is necessary to stop all MTG applications. This should be done by stopping the systemd services. The following command can be used to list all running MTG-related services:
systemctl list-units --type=service | grep mtgRemoving MTG-Java Package
Before the Adoptium Temurin JRE can be installed, the MTG Java 17 package must be removed. This can be done by running the following commands:
dnf remove mtg-java17apt purge mtg-java17zypper remove mtg-java17Installing Adoptium Temurin JRE
Adoptium provides Linux package repositories for Red Hat, Ubuntu, and openSUSE Leap. The official instructions on how to add the repositories can be found here.
| As of May 2025, Adoptium does not provide an official repository for openSUSE Leap 15.6 - The current workaround is to change the URL in the repository file to use the openSUSE Leap 15.5 repository instead. |
Once the repository has been successfully configured, the Adoptium Temurin JRE package can be installed via the following commands:
dnf install temurin-17-jreapt install temurin-17-jrezypper install temurin-17-jreThe Java installation can be verified by running the command java --version.
