Only openjdk-11-jdk and newer seem to be available. Is there any way to install the OpenJDK 8? Preferably without adding a PPA.

    You may download `jdk-8u212-linux-x64.tar.gz` (185.98 MB) directly from https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and install it at `/opt/jvm` or any where you wish. Please note that this **NOT** `open jdk 8`. – Marmayogi Apr 18 '19 at 20:07
  • @Marmayogi That wouldn't enable auto-updates. Preferably a solution would include an auto-update feature. – Andrew Apr 18 '19 at 20:09
  • That is known thing @Andrew. It is up to questioner's choice. I too installed Oracle JDK 11 on /opt/jvm. Now JDK-12 is out and I just downloaded little while ago and going to install. One advantage is that I can switch between JDK-11 and JDK-12 whenever need arises. – Marmayogi Apr 18 '19 at 20:13
  • I made it very clear @FliegendeWurst that the download URL is for Oracle JDK-8 and **NOT** for `open jdk 8`. – Marmayogi Apr 18 '19 at 20:18

    I was hoping to find a PPA from the fine people over at https://adoptopenjdk.net - but haven't been able to find one yet. – jocull Apr 19 '19 at 18:10

As of now, 30 April 2019 02:00 UTC, Open JDK 8 and its associated packages have been added back to the normal Ubuntu 19.04 Disco Dingo repositories.

So you can now do the usual 

sudo apt install openjdk-8-jdk

without adding any PPAs or downloading .deb packages.

As an aside, I believe the package was removed from 19.04 (while originally being there) because it was (erroneously?) removed from Debian testing (related bug report) and then cleaned up downstream. It has been re-added today by its maintainer Matthias Klose aka doko.

    I just tried this on 11 May 2019 11:21 BST but it prints `E: Unable to locate package openjdk-8-jdk` - it seems to not be available again? – Philip Eagles May 11 '19 at 10:29
  • I can see from their website that it's in disco-updates in universe (https://packages.ubuntu.com/disco-updates/openjdk-8-jdk). Do you have that enabled in your system? Open "Software & Updates" and on the "Ubuntu Software" tab, enable "...(universe)" and on the "Updates" tab enable "Recommended updates (disco-updates)" – Andrew May 11 '19 at 17:14
  • Thanks, it was the "Recommended updates (disco-updates)" in the "Updates" tab that wasn't enabled - I'm guessing this was because I chose to do a minimal installation rather than full one. – Philip Eagles May 13 '19 at 09:58

While PPA is the preferred method to install JDK 8 in order to get timely updates and fixes, but if you still want to install without PPA, you can download and install JDK 8 from Ubuntu's pool of Universe packages.

  • Download JDK and JRE:

    wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jdk-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jdk_8u191-b12-2ubuntu0.18.10.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jre_8u191-b12-2ubuntu0.18.10.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jre-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb

  • Install using dpkg:

    sudo dpkg -i openjdk-8-jre-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb \
openjdk-8-jre_8u191-b12-2ubuntu0.18.10.1_amd64.deb \
openjdk-8-jdk_8u191-b12-2ubuntu0.18.10.1_amd64.deb \
openjdk-8-jdk-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb

  • Install dependencies:

    sudo apt install -f

If you want to install using PPA, add openjdk-r ppa and install:

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt update
sudo apt install openjdk-8-jdk openjdk-8-jre

Kulfy's answer is working for me. However, I had to make some changes in order to make it work on Ubuntu 19.04.

  1. Download JRE and JDK:

    wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jdk-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jdk_8u191-b12-2ubuntu0.18.10.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jre_8u191-b12-2ubuntu0.18.10.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jre-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb

  2. Try to install using dpkg (\ didn't work for me, just use spaces):

    sudo dpkg -i openjdk-8-jre-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb openjdk-8-jre_8u191-b12-2ubuntu0.18.10.1_amd64.deb openjdk-8-jdk_8u191-b12-2ubuntu0.18.10.1_amd64.deb openjdk-8-jdk-headless_8u191-b12-2ubuntu0.18.10.1_amd64.deb

  3. If you have missing dependencies, and error will be shown. Install the dependencies:

    sudo apt install -f

  4. After installing the dependencies, try to install again (Go to step 2).

  1. Press on left/bottom corner on 'show applications' or 'windows button'
  2. Open Software & Updates
  3. Make sure you have these 2 checked Update Software -> universe

Updates -> disco-update 4. Close(update) 5. Restart Enjoy :)
