How am I getting this Java error for version 6 when I am installing Java 8?

Question

I am trying to install a version of Java of which I know there is no support, but some application complains that it needs Java 6. I wasn't able to install 6, so I tried with Java 8. My system is running Ubuntu 14.04.

I issued these commands

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer

I got this error for Java 6. I removed the folders in /usr/lib/jvm , but I'm still getting this error.

E: Sub-process /usr/bin/dpkg returned an error code (1)

Are there any good alternatives for Java 6 on Ubuntu? Why does the error show things about Java 6 when I am not installing it?

Answer 1

Did you try installing JDK 6 and 7 before 8 like so:

sudo apt-get install oracle-java6-installer
sudo apt-get install oracle-java7-installer

Answer 2

You could use the Zulu JDK from Azul. This is a TCK certified build of OpenJDK and completely free.

Instructions for installation from the repo can be found here:
