How to Install Terraform on Ubuntu 22.04

Terraform, developed by HashiCorp, is an open-source infrastructure as a code software tool. Terraform is a powerful tool used in Ubuntu for infrastructure automation and management. It enables users to define and provision infrastructure resources, such as virtual machines, networks, storage, and more, in a declarative manner.

This means users can specify the desired state of their infrastructure using configuration files, and Terraform handles the process of creating, updating, and destroying resources to match that state.

This guide provides step-by-step instructions on how to install Terraform on Ubuntu 22.04.

How to Install Terraform on Ubuntu 22.04

Method 1: Installing Terraform on Ubuntu 22.04 Using Snap

Step 1: Updating Ubuntu

Before installing Terraform, updating your system’s package index and upgrading existing packages is essential. Open a terminal and run the following commands:

$ sudo apt update && sudo apt upgrade

Step 2: Installing Snap Package Manager

Snap is a universal package manager for Linux distributions, including Ubuntu. You can Install Snap by running the following command if it already didn’t install:

$ sudo apt install snapd

Step 3: Installing Terraform Via Snap

Once Snap is installed, you can easily install Terraform using the following command:

$ sudo snap install terraform --classic

Step 4: Verifying the Installation

After the installation process is complete, verify that Terraform is installed correctly by running the following command:

$ terraform --version

Method 2: Installing Terraform on Ubuntu 22.04 Using Apt

Step 1: Adding HashiCorp GPG Key

Once the package index is updated, you can proceed to install Terraform using the apt package manager. However, it’s worth noting that Terraform may not be available in the default Ubuntu repositories. If you directly try to install it using the apt command, you will get the following error:

$ sudo apt install terraform

In such cases, you would need to add the HashiCorp GPG key and repository to your system:

$ wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg

Step 2: Adding HashiCorp Repository

Next, add the HashiCorp repository to your system’s list of package sources by running the following command:

$ sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"

Step 3: Update Package Again

After adding the repository, it’s necessary to update the package index once more to include the newly added repository:

$ sudo apt update

Step 4: Installing Terraform

Now after following the previous steps you should be able to install Terraform using the apt package manager:

$ sudo apt install terraform

Step 5: Verifying Installation

You can verify the installation of Terraform by executing the following command:

$ terraform --version
