i recently tried installed java 7 on ubuntu 12.04 and i think i screwed something up
I followed the instructions given here.
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
