Unsuccessful installation of Node Red on Ubuntu 16.04 LTS

General

I'm trying to install Node Red in a desktop with Ubuntu 16.04 LTS operating system.
Already successfully installed Node.js (v4.2.6) and npm (v3.5.2).
But when I try to install Node Red using the command sudo npm install -g --unsafe-perm node-red, the things start to not working.

Can someone help me?
The error is as follows:

Hi,

You need a more recent version of Node. We recommend Node 8.x.

In fact the easiest way is to use the Pi install script in the installation docs. It works fine on Ubuntu.

Thank you both.
I have performed the following procedures to be able to update Node.js to version 8.x:

sudo apt install curl

curl -sL https://deb.nodesource.com/setup_8.x | sudo bash -

sudo apt-get install -y nodejs

After that, the Node.js and npm was updated, respectively, to v8.15.0 and 6.4.1 and I could install the Node Red using Pi install script as @Colin sad. The script was:

bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)

The sources were:

https://nodered.org/docs/hardware/raspberrypi

Too late now, but just for reference, the Pi script would have upgraded node.js for you (using the same technique you did).
