Upgrading nodejs in ubuntu 14.04

My machine has 5.x installed and had lot of trouble updating it to 8.x. Below are the steps I followed to upgrade nodejs from 5.x to 8.x

#add the new source list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 68576280
 sudo apt-add-repository "deb https://deb.nodesource.com/node_8.x $(lsb_release -sc) main"

sudo apt-get update

#Remove the previous installation

sudo apt-get purge nodejs npm
 #Verify if proper version is going to be installed
apt-cache policy <package>

#Install new version

sudo apt-get install -y nodejs
