E: Unable to locate package oracle-java7-installer [Ubuntu 13]

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. 

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 is to do the below.

ahmed@ubuntu:~$ sudo su
root@ubuntu:~$ echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" > /etc/apt/sources.list.d/webupd8team-java.list
root@ubuntu:~$ echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" >> /etc/apt/sources.list.d/webupd8team-java.list
root@ubuntu:~$ apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886
root@ubuntu:~$ apt-get update
root@ubuntu:~$ apt-get install oracle-java7-installer
root@ubuntu:~$ exit
ahmed@ubuntu:~$ 
ahmed@ubuntu:~$ java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
ahmed@ubuntu:~$

 

All done. !!!
