  • *"but its not working"* is not a useful problem description. Start by reading [When using sudo with redirection, I get 'permission denied'](http://askubuntu.com/questions/230476/when-using-sudo-with-redirection-i-get-permission-denied) – steeldriver Mar 10 '17 at 17:52
  • Why a brittle 'installation script' instead of creating a real package? – user535733 Mar 10 '17 at 18:11
  • Try to add some more useful information such as the errors that you are getting when you execute the script. Otherwise it might become a lot of guess work. – akxer Mar 10 '17 at 18:25

The immediate solution is to take sudo out of the script and run the script using sudo script-file.

A perhaps better solution is to use Web Upd8's package that takes care of installing Oracle's Java 8 for you, including updating it via apt upgrade when new versions come out.

This can be done in the terminal with:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
