The OpenJRE is very easy to install as it is available in the default Ubuntu package repositories (where software is downloaded from). The general instructions I followed for installation were sourced from a Digital Ocean tutorial - who have excellent tutorials on Linux system administration topics. For a more detailed discussion, there is a good article called Oracle JDK builds vs. Open JRE: The open source version of the Oracle JREįor the sake of this post, there is very little difference between the two versions - apart from one is open source.Oracle JRE: The Oracle JRE (the people who make Java).On Ubuntu Linux (and most other Linux-based operating systems) you have two different options for the JRE installation: In this tutorial, I installed the JRE as it has a smaller installation footprint. To play Old School RuneScape, you can use the JRE or JDK (you can use the JDK because it contains the JRE!).

JDK (Java Development Kit): Used to run and develop (read program) Java applications.JRE (Java Runtime Environment): Used to run Java applications.To keep this as short as possible, there are two primary Java versions that you can install: The different Java versions available complex and difficult to understand for someone who is not a Java developer.

The general process to install and run RuneLite on Linux is pretty simple, but there are some tweaks and configurations I made to make RuneLite available for any user (system-wide installation) and easy to run using a simple a command alias or desktop shortcut. This post documents how I installed RuneLite on a fresh Ubuntu Desktop Linux version 18.04 system.
