This is a quick note that shows how to update Oracle Java 8 on Raspbian / Raspberry Pi.

By default, Raspbian has the following Java 8 Oracle package:

root@rpi3server:~# dpkg --list | grep  oracle-java8-jdk
ii  oracle-java8-jdk 8u65 armhf Java™ Platform, Standard Edition 8 Development Kit

root@rpi3server:~ $ java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode)

And the default Raspbian repositories do not regurarly update this package.

We need to use the Oracle Java Installer from

Install the repository key, from

root@rpi3server:~# gpg --keyserver --recv EEA14886
root@rpi3server:~# gpg --export --armor EEA14886 | sudo apt-key add -

Add the repository URLs to the APT sources config file /etc/apt/sources.list, using your favourite text editor.

root@rpi3server:~# emacs /etc/apt/sources.list

deb trusty main
deb-src trusty main

Update the repositories.

root@rpi3server:~# apt-get update

Use the installer package to automatically update Oracle Java. You must accept the license messages and confirm the installation when prompted.

root@rpi3server:~# apt-get install oracle-java8-installer

Set the updated Oracle Java as default.

root@rpi3server:~# apt install oracle-java8-set-default

And finally, confirm that everything is fine.

root@rpi3server:~# java -version
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) Client VM (build 25.144-b01, mixed mode)

Important: Note that all commands are executed as root. If you do not have access to a root shell (by default you are not allowed to use it), use sudo to execute them (prefix all commands with "sudo").
