How To Install Node.js on Ubuntu 20.04 LTS

Install Node.js on Ubuntu 20.04

In this tutorial, we will show you how to install Node.js on Ubuntu 20.04 LTS server. For those of you who didn’t know, Node.js is a cross-platform JavaScript runtime environment built on Chrome’s JavaScript, designed to execute JavaScript code on the server-side. It is generally used to build back-end applications, but it is also popular as a full-stack and front-end solution. npm is the default package manager for Node.js and the world’s largest software registry.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Node.js on a Ubuntu 20.04 (Focal Fossa) server.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Node.js on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install curl wget gnupg2

Step 2. Installing Node.js on Ubuntu 20.04.

  • Install Node.js and npm from Node Source

You simply need to add the PPA for the version you want to install:

curl -sL | sudo -E bash -

To install, run the commands below:

sudo apt install nodejs

Once done, verify the installation by running:

node --version
npm --version
  • Install Node.js and npm via Snap

Another way to install Node.js is via Snap package management:

sudo apt install snapd
sudo snap install node --channel=14/stable --classic
  • Install Node.js and npm using NVM

NVM (Node Version Manager) is a bash script that allows you to manage multiple Node.js versions on a per-user basis.

So, first, we’ll want to update our local repository index and then install libssl-dev and build-essential. That can be done by running the below commands in a terminal or shell:

apt-get update
apt-get install build-essential libssl-dev

Once those are installed you need to download the setup script for NVM. Typically you can grab this from their Github page. Though at the time of this writing the newest version is in the command below:

curl -o- | bash

Verify that the script is indeed the one you want and then run:


To begin the installation of NVM. Once it finishes you will need to reload your profile to have your changes take effect without logging back into your server again. Run the command:

source ~/.profile

Now as we have nvm installed, we can install isolated Node.js versions. To find out the versions of Node.js that are available for installation, we need to type:

[ ~]# nvm ls-remote
. . .
       v12.13.0   (LTS: Erbium)
       v12.13.1   (LTS: Erbium)
       v12.14.0   (LTS: Erbium)
       v12.14.1   (LTS: Erbium)
       v12.15.0   (LTS: Erbium)
       v12.16.0   (LTS: Erbium)
       v12.16.1   (LTS: Erbium)
       v12.16.2   (LTS: Erbium)
       v12.16.3   (Latest LTS: Erbium)
