Use this tutorial to Install Oracle Java 8 on Ubuntu 18.04 LTS, 16.04 LTS, 14.04 LTS and LinuxMint 19, 18 using PPA. Follow the below steps to Install Oracle Java 8 on Ubuntu command line.
Step 1 – Install Oracle Java 8 on Ubuntu
You need to enable additional repository to your system to install Java 8 on Ubuntu VPS. After that install Oracle Java 8 on an Ubuntu system using apt-get. This repository contains a package named oracle-java8-installer, Which is not an actual Java package. Instead of that, this package contains a script to install Java on Ubuntu.
Run below commands to install Java 8 on Ubuntu and LinuxMint.
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer
Step 2 – Verify Java Inatallation
The apt repository also provides package oracle-java8-set-default to set Java 8 as your default Java version. This package will be installed along with Java installation. To make sure run below command.
sudo apt-get install oracle-java8-set-default
After successfully installing Oracle Java 8 using the above steps, Let’s verify the installed version using the following command.
java -version java version " 1.8.0_201 " Java(TM) SE Runtime Environment (build 1.8.0_201-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
Step 3 – Setup JAVA_HOME and JRE_HOME Variable
After installing Java on Linux system, You must have to set JAVA_HOME and JRE_HOME environment variables. Which is used by many Java applications to find Java libraries during runtime. You can set these variables in /etc/environment file using the following command.
cat >> /etc/environment <<EOL JAVA_HOME=/usr/lib/jvm/java-8-oracle JRE_HOME=/usr/lib/jvm/java-8-oracle/jre EOL
All done, you have successfully installed Java 8 on a Linux system. You may also need to install Tomcat server to run your Java web application. Use our another tutorial to Install Tomcat 7 or Install Tomcat 8 or Install Tomcat 9 on Ubuntu, Debian, and LinuxMint systems.

It’s not working and it won’t work. You need to update your article. Oracle has made it mandatory to create an account and download the required version. The PPA method is deprecated and it won’t work.
TIP: Make sure you download the binary version or the Oracle 8 JDK.
