How to completely remove a oracle jdk that didn't install properly?

rated 0 times [ 41] [ 0] / answers: 1 / hits: 80810 / 2 Years ago, fri, october 28, 2022, 10:56:36

I recently installed a oracle jdk from a webupd8ppa on Ubuntu 12.04 beta, but apparently it didn't work out, and now it is giving me errors at every update or install I make, even after deactivating the ppa from my sources.

This is what I get when I try uninstalling from USC:

I was having the same problem on Ubuntu 11.10, tried all of the same solutions, none of which worked for me either. I found this on another discussion board and it appears to have worked for me:

If you want to remove oracle-jdk7-installer, you can simply go to
/var/lib/dpkg/info/ It takes some time to load, and delete all files
which starts with oracle-java7***** there was ~6files, then go to
Synaptic and simply locate same oracle-jdk and click remove/completly
remove.

This is where I found it: http://ubuntuforums.org/showthread.php?p=11821814

Good luck!

Edit: here are the 3 steps to easily do this:

Open a terminal (ctrl + alt + T) and type those two commands successively:

cd /var/lib/dpkg/info/

sudo rm oracle-java7-installer*

Open synaptic, search for "oracle-java7-installer", mark it for complete removal and click "apply".

Edit:
For those that don't have synaptic installed, after you rm the oracle installer files, just do:

sudo apt-get purge oracle-java7-installer

And you should be good.

edit:
worked on ubuntu 12.04 LTS as well
