This is the way I installed nodejs in ubuntu 14.04 LTS:
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get install nodejs
When I checked the node version with this:
node -v
I get this
v0.10.37
But the latest version is 4.2.6 and 5.5.0. How can I get the latest or update version?
sudo apt-get install curl
For Node.js v4
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs
For Node.js v5:
curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
sudo apt-get install -y nodejs
Node.js v6:

sudo apt-get install -y nodejs
Node.js v7:

sudo apt-get install -y nodejs
