i recently tried installed java 7 on ubuntu 12.04 and i think i screwed something up

First you need to remove openjdk for this run the following command from your terminal



sudo apt-get purge openjdk*

Now you can install Java7 by adding the following repository:



sudo add-apt-repository ppa:eugenesan/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

Now everytime i install a new program i get the following error:

Download done.

sha256sum mismatch jdk-7u3-linux-x64.tar.gz

Oracle JDK 7 is NOT installed.

dpkg: error processing oracle-java7-installer (--configure):

 subprocess installed post-installation script returned error exit status 1

Setting up python-central (0.6.17ubuntu1) ...

Setting up python-eggtrayicon (2.25.3-11) ...

Setting up gmail-notify (1.6.1.1-1ubuntu1) ...

Processing triggers for python-central ...

Errors were encountered while processing:

 oracle-java7-installer

Error in function:

However.The program seems to install and work just fine so it doesn't seem to be a problem preventing me from doing anything

So then i reinstalled openjdk by going:

sudo apt-get install openjdk*

But i still get the same error.

going:

sudo apt-get install oracle-java7-installer gives me the same error.

What is going on?

Please let me know if this is clear or not and ill try to explain my issue better
