Solution

Uninstall NodeJS from Ubuntu

The command will remove the package but retain the configuration files.

sudo apt-get remove nodejs
sudo apt-get autoremove

To remove both the package and the configuration files run:

sudo apt-get purge nodejs
sudo apt-get autoremove

Install NodeJS on Ubuntu

Adding the NodeJS PPA to Ubuntu

sudo apt-get install software-properties-common
curl -sL https://deb.nodesource.com/setup_11.x | sudo -E bash -

After successfully adding the NodeJS PPA, It’s time now to install NodeJS using the command below.

sudo apt-get install nodejs

Verfiying the version of NodeJS and NPM

node -v
npm -v
