How to install a specific version of Node on Ubuntu?

The n module worked for me.

Run this code to clear npm’s cache, install n, and install the latest stable version of Node:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

See: http://www.hostingadvice.com/how-to/update-node-js-latest-version/
And: https://www.npmjs.com/package/n

To install a specific version of node:

sudo n 6.11.2

To check what version:

node -v

You might need to restart

Chris Lea has 0.8.23 in his ppa repo.

This package let you add a repository to apt-get: (You can also do this manually)

sudo apt-get install software-properties-common

Add Chris Lea's repository:

sudo apt-add-repository ppa:chris-lea/node.js-legacy

Update apt-get:

sudo apt-get update

Install Node.js:

sudo apt-get install nodejs=0.8.23-1chl1~precise1

I think (feel free to edit) the version number is optional if you only add node.js-legacy. If you add both legacy and ppa/chris-lea/node.js you most likely need to add the version.
