 sudo apt-get update && sudo apt-get install -y gnupg software-properties-common
```

Install the HashiCorp [GPG key](https://apt.releases.hashicorp.com/gpg)

```shell-session
wget -O- https://apt.releases.hashicorp.com/gpg | \
gpg --dearmor | \
sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg > /dev/null
```

Verify the key's fingerprint.

```shell-session
 gpg --no-default-keyring \
--keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg \
--fingerprint
```

```shell-session
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] \
https://apt.releases.hashicorp.com $(lsb_release -cs) main" | \
sudo tee /etc/apt/sources.list.d/hashicorp.list
```

Download the package information from HashiCorp.

```shell-session
 sudo apt update
```

Install Terraform from the new repository.

```shell-session
 sudo apt-get install terraform
```

Verify that the installation worked by opening a new terminal session and listing Terraform's available subcommands.

```shell-session
 terraform -help
```

Add any subcommand to `terraform -help` to learn more about what it does and available options.

```shell-session
 terraform -help plan
