In this guide, we will show you three different ways of getting Node.js installed on an Ubuntu 22.04 server:
- using apt to install the nodejs package from Ubuntu’s default software repository
- using apt with an alternate PPA software repository to install specific versions of the nodejs package
- installing nvm, the Node Version Manager, and using it to install and manage multiple versions of Node.js
For many users, using apt with the default repo will be sufficient. If you need specific newer (or legacy) versions of Node, you should use the PPA repository. If you are actively developing Node applications and need to switch between node versions frequently, choose the nvm method.
This guide assumes that you are using Ubuntu 22.04. Before you begin, you should have a non-root user account with sudo privileges set up on your system. You can learn how to do this by following the Ubuntu 22.04 initial server setup tutorial.
If you would prefer to follow this tutorial using a terminal in your browser, click the Launch an Interactive Terminal! button to get started. You’ll be able to experiment with and run all the commands directly in your browser.
Option 1 — Installing Node.js with Apt from the Default Repositories
Ubuntu 22.04 contains a version of Node.js in its default repositories that can be used to provide a consistent experience across multiple systems. At the time of writing, the version in the repositories is 12.22.5. This will not be the latest version, but it should be stable and sufficient for quick experimentation with the language.
Warning: the version of Node.js included with Ubuntu 22.04, version 12.22.9, is an LTS, or “long-term support” release. It is technically outdated, but should be supported until the release of Ubuntu 24.04.
To get this version, you can use the apt package manager. Refresh your local package index first by typing:
- sudo apt update
Then install Node.js:
- sudo apt install nodejs
Press Y when prompted to confirm installation. If you are prompted to restart any services, press ENTER to accept the defaults and continue. Check that the install was successful by querying node for its version number:
- node -v
If the package in the repositories suits your needs, this is all you need to do to get set up with Node.js. In most cases, you’ll also want to also install npm, the Node.js package manager. You can do this by installing the npm package with apt:
- sudo apt install npm
This will allow you to install modules and packages to use with Node.js.
At this point you have successfully installed Node.js and npm using apt and the default Ubuntu software repositories. The next section will show how to use an alternate repository to install different versions of Node.js.
Option 2 — Installing Node.js with Apt Using a NodeSource PPA
To install a different version of Node.js, you can use a PPA (personal package archive) maintained by NodeSource. These PPAs have more versions of Node.js available than the official Ubuntu repositories. Node.js v14, v16, and v17 are available as of the time of writing.
First, we will install the PPA in order to get access to its packages. From your home directory, use curl to retrieve the installation script for your preferred version, making sure to replace 17.x with your preferred version string (if different).
- cd ~
- curl -sL https://deb.nodesource.com/setup_17.x -o nodesource_setup.sh
Refer to the NodeSource documentation for more information on the available versions.
You can inspect the contents of the downloaded script with nano (or your preferred text editor):
- nano nodesource_setup.sh
Running third party shell scripts is not always considered a best practice, but in this case, NodeSource implements their own logic in order to ensure the correct commands are being passed to your package manager based on distro and version requirements. If you are satisfied that the script is safe to run, exit your editor, then run the script with sudo:
- sudo bash nodesource_setup.sh
The PPA will be added to your configuration and your local package cache will be updated automatically. You can now install the Node.js package in the same way you did in the previous section. It may be a good idea to fully remove your older Node.js packages before installing the new version, by using sudo apt remove nodejs npm. This will not affect your configurations at all, only the installed versions. Third party PPAs don’t always package their software in a way that works as a direct upgrade over stock packages, and if you have trouble, you can always try to revert to a clean slate.
- sudo apt install nodejs
Verify that you’ve installed the new version by running node with the -v version flag:
- node -v
The NodeSource nodejs package contains both the node binary and npm, so you don’t need to install npm separately.
At this point you have successfully installed Node.js and npm using apt and the NodeSource PPA. The next section will show how to use the Node Version Manager to install and manage multiple versions of Node.js.
Option 3 — Installing Node Using the Node Version Manager
Another way of installing Node.js that is particularly flexible is to use nvm, the Node Version Manager. This piece of software allows you to install and maintain many different independent versions of Node.js, and their associated Node packages, at the same time.
To install NVM on your Ubuntu 22.04 machine, visit the project’s GitHub page. Copy the curl command from the README file that displays on the main page. This will get you the most recent version of the installation script.
Before piping the command through to bash, it is always a good idea to audit the script to make sure it isn’t doing anything you don’t agree with. You can do that by removing the | bash segment at the end of the curl command:
- curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh
Take a look and make sure you are comfortable with the changes it is making. When you are satisfied, run the command again with | bash appended at the end. The URL you use will change depending on the latest version of nvm, but as of right now, the script can be downloaded and executed by typing:
- curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
This will install the nvm script to your user account. To use it, you must first source your .bashrc file:
- source ~/.bashrc
Now, you can ask NVM which versions of Node are available:
- nvm list-remote
Output. . . v16.11.1 v16.12.0 v16.13.0 (LTS: Gallium) v16.13.1 (LTS: Gallium) v16.13.2 (LTS: Gallium) v16.14.0 (Latest LTS: Gallium) v17.0.0 v17.0.1 v17.1.0 v17.2.0 v17.3.0 v17.3.1 v17.4.0 v17.5.0 v17.6.0
It’s a very long list! You can install a version of Node by typing any of the release versions you see. For instance, to get version v16.14.0 (another LTS release), you can type:
- nvm install v16.14.0
You can see the different versions you have installed by typing:
Output-> v16.14.0 default -> v16.14.0 iojs -> N/A (default) unstable -> N/A (default) node -> stable (-> v16.14.0) (default) stable -> 16.14 (-> v16.14.0) (default) lts/* -> lts/gallium (-> v16.14.0) lts/argon -> v4.9.1 (-> N/A) lts/boron -> v6.17.1 (-> N/A) lts/carbon -> v8.17.0 (-> N/A) lts/dubnium -> v10.24.1 (-> N/A) lts/erbium -> v12.22.10 (-> N/A) lts/fermium -> v14.19.0 (-> N/A) lts/gallium -> v16.14.0
This shows the currently active version on the first line (-> v16.14.0), followed by some named aliases and the versions that those aliases point to.
Note: if you also have a version of Node.js installed through apt, you may see a system entry here. You can always activate the system-installed version of Node using nvm use system.
We can install a release based on these aliases as well. For instance, to install fermium, run the following:
- nvm install lts/fermium
OutputDownloading and installing node v14.19.0...

Now using node v14.19.0 (npm v6.14.16)
You can verify that the install was successful using the same technique from the other sections, by typing:
- node -v
The correct version of Node is installed on our machine as we expected. A compatible version of npm is also available.
There are a quite a few ways to get up and running with Node.js on your Ubuntu 22.04 server. Your circumstances will dictate which of the above methods is best for your needs. While using the packaged version in Ubuntu’s repository is the easiest method, using nvm or a NodeSource PPA offers additional flexibility.
