How To Install Java on Ubuntu 19.04 Disco Dingo

Install Java on Ubuntu 19.04

In this tutorial, we will show you how to install Java on Ubuntu 19.04. For those of you who didn’t know, Java is a programming language and computing platform. It was first released by Sun Microsystems in 1995. Many programs and scripts require Java to run, but usually, Java is not installed by default on a VPS or Dedicated Server.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of JRE (Java Runtime Environment) and JDK (Java Development Kit) on Ubuntu 19.04 Disco Dingo.


  • A server running one of the following operating systems: Ubuntu 19.04 (Disco Dingo).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Java on Ubuntu 19.04 Disco Dingo

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Java on Ubuntu 19.04

  • Method 1.

Using Webupd8 Team’s PPA repository we can install Java on Ubuntu automatically using the apt command:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java13-installer

To set Oracle JDK13 as default, install the “oracle-java13-set-default” package:

sudo apt install oracle-java13-set-default

Confirm your Java version:

$ java -version
java version "12.0.1" 2019-12-16
Java(TM) SE Runtime Environment (build 12.0.1+12)
Java HotSpot(TM) 64-Bit Server VM (build 12.0.1+12, mixed mode, sharing)

Set Java environment:

nano /etc/profile.d/


export JAVA_HOME=/usr/lib/jvm/java-13-oracle
export PATH=$PATH:$JAVA_HOME/bin

Update your environment:

source /etc/profile.d/
  • Method 2.

Run the following commands to install the Oracle JDK by Oracle:

sudo apt install openjdk-12-jdk

Now, run the following command to check whether OpenJDK is working correctly:

$ java -version
