In order to get access to the latest version then first, you need to install the PPA. For that you need to make sure that you are in your home directory, and use curl to regain the installation script, and finally, you can replace 8.x with your preferred node.js version:

$ cd ~
$ curl -sL https://deb.nodesource.com/setup_8.x -o nodesource_setup.sh

You can examine the contents of the script with a text editor:

$ nano nodesource_setup.sh

$ npm –v
