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

Question

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 also tried "remove completely" from synaptic but it doesn't work either.

Thank you for your help in advance!

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

Add webupd8 ppa again

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Open the terminal and type:

  sudo apt-get update
  sudo apt-get install -f

Then purge the ppa using ppa purge

sudo apt-get install ppa-purge
sudo ppa-purge ppa:webupd8team/java

1st things 1st you could try the following:

sudo apt-get remove package_name

If that doesn't work because you said that the package was not completely installed then doing the sudo purge command that pjtatlow should fix the issue.

Also I am attaching an apt-get cheat sheet for future reference for you.

If you encountered configuration error when installing a package in Ubuntu,you will get this error message every time when you installing an other package.It’s very annoying and there is a command to delete this mis-configured package. Run this in terminal(Applications/Accessories/Terminal):

sudo apt-get purge $(dpkg -l|grep ^rc|awk '{ print $2 }')
