Installing Java6 JDK on Ubuntu 12.04

UPDATE: [01-May-2012] It appears that this PPA repo is currently broken (does not allow to get GPG key and has unmet dependencies on x84_64). It appears that the install on i386 systems does work anyway if you ignore the GPG key error, but I wouldn’t install in that case as PPA installs are security risk enough without GPG errors.

UPDATE: [11-May-2012] The reason the PPA does not work is that it has been disabled by Ubuntu due to a licensing issue with (not hard to guess) Oracle. have however created a script (hosted on Github) to allow the automated update of Java 6 for those who still require it as a dependency.

wget -O
chmod +x
sudo ./

Hat tip to Martin Wimpress from Flexion !

UPDATE: [07-Aug-2012] Thanks to a comment from Pierre-Yves Langlois this seems to be the best method (uses the latest version of the Flexion script from Github rather than the version referenced above)

sudo apt-get purge sun-java* #You need to do that if you want the mozilla plugin to work without conflict with java7 for instance.
mkdir ~/src
cd ~/src
git clone
cd ~/src/oab-java6
sudo ./

Then when its finished, install java:
sudo apt-get install sun-java6-plugin sun-java6-jre sun-java6-bin sun-java6-jdk

You can follow the installation process with:
tail -f ~/src/oab-java6/

Note: If you do not need Java 6 it’s much safer to stick to the current Oracle Java 7 release.

This is an update to the Java6 install on 11.10 since the previous PPA repository has not been updated. To install on Precise Pangolin you need to add the following repository

sudo add-apt-repository ppa:flexiondotorg/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin

EDIT: [01-May-2012] since there seem to be many comments about the repo not working here’s the manual process (since I can’t find any working PPA that is actually maintained).

Download the Linux .bin install (32 or 64bit) from Oracle’s site Java Archive.

#change permissions to allow execute
chmod a+x jdk-6u[current_version_number]-linux-i586.bin
#run the installer file

Note: you obviously need to also maintain the Java6 updated manually.

Installing Java6 JDK on Ubuntu 11.10

UPDATE: To install on 12.04 (Precise Pangolin) you need a different PPA.

Since sun-java6-jdk has been removed from the default Ubuntu 11.10 (Oneiric Ocelot) repositories you need to add a PPA repository (unless you want to install by hand)

sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin
