Was installing Java today, this is an easy install thanks to ppa:webupd8team/java, but when I tried it was not working, but has worked for me all this while.
Little goggling around found me a solution. Here is full conversation if you wanted to have a look http://ubuntuforums.org/showthread.php?t=2048793
Installing JAVA on Ubuntu is simple. Do the below to add the repository and run the below command ‘sudo apt-get install oracle-java7-installer’ to install.
Error.
ahmed@ubuntu:~$ sudo add-apt-repository ppa:webupd8team/java
ahmed@ubuntu:~$ sudo apt-get update
ahmed@ubuntu:~$ sudo apt-get install oracle-java7-installer
ahmed@ubuntu:~$ sudo apt-get install oracle-java7-installer

Solution.
Elevating to root.

Adding to deb.
root@ubuntu:~# echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" \
> /etc/apt/sources.list.d/webupd8team-java.list
Adding to deb-src
root@ubuntu:~# echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" \
>> /etc/apt/sources.list.d/webupd8team-java.list
Making sure we have the key as well.
root@ubuntu:~# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886
Lets update our apt-get repository.
root@ubuntu:~# apt-get update
Now Install Oracle Java
root@ubuntu:~# apt-get install oracle-java7-installer
<..loads of verbose...>
root@ubuntu:~# exit
