If you’re a developer, you’re probably familiar with the importance of package managers. Yarn is a popular package manager that is designed to be fast, reliable, and secure. It was developed by Facebook and is used by many developers around the world. In this guide, we’ll show you how to install Yarn on Ubuntu 20.04, a popular Linux distribution.
Before we dive into the installation process, let’s take a quick look at what Yarn is and why you should consider using it. Yarn is a package manager that was created to solve some of the problems that developers faced when using other package managers like npm. Yarn is faster than npm and is designed to be more reliable. It also includes some powerful features like offline caching and deterministic installs.
If you’re working on a project that requires a lot of packages, Yarn can save you a lot of time and headaches. It’s also a good choice if you’re concerned about security, as Yarn uses checksums to ensure that packages are not tampered with.

Updating the Package Index
<!– /wp:heading –>
Before we install Yarn, we need to update the package index on our system. This ensures that we have access to the latest packages and dependencies. To update the package index, open a terminal window and enter the following command:
<!– wp:code –>
sudo apt update
<!– /wp:code –>
This will update the package index on your system.
<!– wp:heading –>
Installing Node.js
<!– /wp:heading –>
Yarn requires Node.js to be installed on your system. If you don’t already have Node.js installed, you can install it using the following command:
<!– wp:code –>
sudo apt install nodejs
<!– /wp:code –>
This will install the latest version of Node.js on your system. Once the installation is complete, you can verify that Node.js is installed by running the following command:
<!– wp:code –>
node -v
<!– /wp:code –>
This will display the version of Node.js that is installed on your system.
<!– wp:heading –>
Installing npm
<!– /wp:heading –>
npm is another popular package manager that is used by many developers. Yarn uses npm to manage some of its dependencies, so we need to install npm before we can install Yarn. To install npm, enter the following command:
<!– wp:code –>
sudo apt install npm
<!– /wp:code –>
This will install the latest version of npm on your system.
<!– wp:heading –>
Importing the Yarn GPG Key
<!– /wp:heading –>
Before we can install Yarn, we need to import the Yarn GPG key. This key is used to verify the authenticity of the packages that we will be installing. To import the Yarn GPG key, enter the following command:
<!– wp:code –>
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
<!– /wp:code –>
This will import the Yarn GPG key on your system.
<!– wp:heading –>
Adding the Yarn Repository
<!– /wp:heading –>
Next, we need to add the Yarn repository to our system. This repository contains the packages that we will be installing. To add the Yarn repository, enter the following command:
<!– wp:code –>
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
<!– /wp:code –>
This will add the Yarn repository to your system.
<!– wp:heading –>
Updating the Package Index Again
<!– /wp:heading –>
Now that we’ve added the Yarn repository, we need to update the package index again to ensure that we have access to the Yarn packages. To update the package index, enter the following command:
<!– wp:code –>
sudo apt update
<!– /wp:code –>
This will update the package index on your system.
<!– wp:heading –>
Installing Yarn
<!– /wp:heading –>
Finally, we can install Yarn using the following command:
<!– wp:code –>
sudo apt install yarn
<!– /wp:code –>
This will install the latest version of Yarn on your system.
<!– wp:heading –>
Verifying the Installation
<!– /wp:heading –>
To verify that Yarn has been installed correctly, you can run the following command:
<!– wp:code –>
yarn --version
<!– /wp:code –>
This will display the version of Yarn that is installed on your system. If you see a version number, then Yarn has been installed correctly.
<!– wp:heading –>
Troubleshooting
<!– /wp:heading –>
If you run into any issues during the installation process, there are a few things you can try. First, make sure that you have followed all of the steps in this guide correctly. If you’re still having issues, you can try uninstalling Yarn and then reinstalling it. You can also try updating your system to the latest version of Ubuntu.
