In this guide, we will show you three different ways of getting Node.js installed on an Ubuntu 20.04 server:
aptto install the
nodejspackage from Ubuntu’s default software repository
aptwith an alternate PPA software repository to install specific versions of the
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
To follow this guide, you will need an Ubuntu 20.04 server set up. 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 20.04 initial server setup tutorial.
Ubuntu 20.04 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 10.19. 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 20.04, version 10.19, is now unsupported and unmaintained. You should not use this version in production, and should refer to one of the other sections in this tutorial to install a more recent version of Node.
To get this version, you can use the
apt package manager. Refresh your local package index first:
- sudo apt update
Then install Node.js:
- sudo apt install nodejs
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
- sudo apt install npm
This allows you to install modules and packages to use with Node.js.
At this point, you have successfully installed Node.js and
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.
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 v16 and v18 are available as of the time of writing.
First, install the PPA 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
16.x with your preferred version string (if different):
- cd ~
- curl -sL https://deb.nodesource.com/setup_16.x -o /tmp/nodesource_setup.sh
Refer to the NodeSource documentation for more information on the available versions.
Inspect the contents of the downloaded script with
nano or your preferred text editor:
- nano /tmp/nodesource_setup.sh
When you are satisfied that the script is safe to run, exit your editor. Then run the script with
- sudo bash /tmp/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:
- sudo apt install nodejs
Verify that you’ve installed the new version by running
node with the
-v version flag:
- node -v
nodejs package contains both the
node binary and
npm, so you don’t need to install
At this point, you have successfully installed Node.js and
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.
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 20.04 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 -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh
Review the script 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 with the following:
- curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
This will install the
nvm script to your user account. To use it, you must first source your
- source ~/.bashrc
Now, you can ask NVM which versions of Node are available:
- nvm list-remote
Output. . . v18.0.0 v18.1.0 v18.2.0 v18.3.0 v18.4.0 v18.5.0 v18.6.0 v18.7.0 v18.8.0 v18.9.0 v18.9.1 v18.10.0 v18.11.0 v18.12.0 (LTS: Hydrogen) v18.12.1 (LTS: Hydrogen) v18.13.0 (Latest LTS: Hydrogen) v19.0.0 v19.0.1 v19.1.0 v19.2.0 v19.3.0 v19.4.0
It’s a very long list. You can install a version of Node by writing in any of the release versions listed. For instance, to get version v14.10.0, you can run:
- nvm install v14.10.0
You can view the different versions you have installed by listing them:
Output-> v14.10.0 v14.21.2 default -> v14.10.0 iojs -> N/A (default) unstable -> N/A (default) node -> stable (-> v14.21.2) (default) stable -> 14.21 (-> v14.21.2) (default) . . .
This shows the currently active version on the first line (
-> v14.10.0), 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 receive a
system entry here. You can always activate the system-installed version of Node using
nvm use system.
Additionally, there are aliases for the various long-term support (or LTS) releases of Node:
Outputlts/* -> lts/hydrogen (-> N/A) 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 -> v12.22.12 (-> N/A) lts/fermium -> v14.21.2 lts/gallium -> v16.19.0 (-> N/A) lts/hydrogen -> v18.13.0 (-> N/A)
You can install a release based on these aliases as well. For instance, to install the latest long-term support version,
hydrogen, run the following:
- nvm install lts/hydrogen
OutputDownloading and installing node v18.13.0... . . . Now using node v18.13.0 (npm v8.19.3)
You can switch between installed versions with
- nvm use v14.10.0
OutputNow using node v14.10.0 (npm v6.14.8) ``` You can verify that the install was successful using the same technique from the other sections: ```command node -v
The correct version of Node is installed on your machine as expected. A compatible version of
npm is also available.
You can uninstall Node.js using
nvm, depending on how it was installed. To remove the version from the system repositories, use
- sudo apt remove nodejs
apt remove retains any local configuration files that were created since installation. If you don’t want to save the configuration files for later use, use
- sudo apt purge nodejs
To uninstall a version of Node.js that you installed using
nvm, first determine whether it is the current active version:
- nvm current
If the version you are targeting is not the current active version, you can run:
- nvm uninstall node_version
OutputUninstalled node node_version
This command will uninstall the selected version of Node.js.
If the version you would like to remove is the current active version, you first need to deactivate
nvm to enable your changes:
- nvm deactivate
Now you can uninstall the current version using the
uninstall command used previously. This removes all files associated with the targeted version of Node.js.
There are quite a few ways to get up and running with Node.js on your Ubuntu 20.04 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 one method, using
nvm or a NodeSource PPA offers additional flexibility.

node -v node: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27’ not found (required by node)
If you’re using a non root user and having issues like this: “E: Failed to fetch http://mirrors.digitalocean.com/ubuntu focal InRelease” Try the command “sudo apt-get update”. If you have problem also with this command then you have to change the fetch link that gives you the error.
Try these commands:
If you type “ls” you should see a “sources.list” file. We need to edit that.
Type: “vim sources.list”
Activate editor by pressing “i” then move to every link that has “mirrors.digitalocean.com” and change it to “archive.ubuntu.com”.
When you finish, press “esc” then “:w !sudo tee % > /dev/null”. File should be saved now.
Try installing nodejs now. Should work fine.
Hope it helps.
In the version of this tutorial for ubuntu 18.04, there are instructions for installing the build essentials package, but not here. This is not required for this version?
If you’re using Option 2, you need to run sudo apt update after you’ve added the PPA to your configuration, otherwise you’ll get an error message about being Unable to locate package node.js…
Thanks Brian. This doc is very clear and complete and helped me a great deal.
If you go with option 1 or 2, you will probably face permission error issues.
In this case, make sure to configure npm to use a different directory.
When following “Option 3 — Installing Node Using the Node Version Manager” you will be unable to “sudo npm”.
This can be fixed by running this command:
If you want the nvm node version to be the default, ie stay set after reboot run this. $ nvm alias default <your version>
I really appreciated the 3 options you gave us. I wonder though… I went with NVM and copied the code snippets to install it. Should I have used sudo with these commands. It appears that nvm was installed but only for my sudo user. I’m hoping (and guessing) this won’t be an issue. Thanks you!
