I have Ubuntu 16.04 (32bit) I have openjdk version "1.8.0_121"

I am getting an error from a makefile saying:

You are attempting to build with the incorrect version
of java.
Your version is: openjdk version "1.8.0_121".
The correct version is: Java SE 1.6.

I have tried

sudo apt-get install openjdk-6-jdk

returned

openjdk-6-jdk has no installation candidate

Tried going to

Wont install because of multiple errors

Done.

Also tried the non rpm version from and got:

./jdk-6u45-linux-i586.bin: 74: ./jdk-6u45-linux-i586.bin: ./install.sfx.17296: not found
Failed to extract the files. Please refer to the Troubleshooting section of
the Installation Instructions on the download page for more information.

Somewhere I found openjdk-6_6b38-1.13.10.orig.tar.gz forget where I got that, but it was complaining I didn't have a JDK home directory.

configure: error: "A JDK home directory could not be found."

Im just digging deeper and nothing is working. Wondering if theres some simple repo that I can get openjdk-6-jdk that will actually work?

Thanks!

OpenJDK 6 is still in Ubuntu Trusty :

If you have a reasonably powerful computer you could consider using Qemu/KVM or VirtualBox and install Ubuntu Trusty (14.04) as a guest VM. That would be the most clean solution in my opinion.

There's also a ppa for OpenJDK 6 which might or might not work in your Xenial install by editing the downloaded sources list file (Changing xenial into trusty) :

In the latter case I recommend to remove the OpenJDK-8 first.

Ok so finally got it to work

I went to and downloaded jdk-6u45-linux-i586.bin

I installed the 32 bit libraries

sudo apt-get install lib32z1

then

chmod +x jdk-6u45-linux-i586.bin
./jdk-6u45-linux-i586.bin

then followed this post How do I install Oracle JDK 6?

and had to add the webupd8 repo and do

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo update-java
java -version
