How to install nodejs 4.* on Ubuntu 14.04

Question

I've been looking at some pages that explain how to install nodejs 4.* on Ubuntu 14.04 but it doesn't install and tells me that I already have the latest version:

$ curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -

$ node --version

There is an error at the end of the curl command but I don't know if that' related. I'm following this guide - https://nodejs.org/en/download/package-manager/ - but other pages seem to be the same. What's wrong?
