Import Waterfox APT Repository on Linux Mint 21 or 20

Step 1: Update Linux Mint Before Installing Waterfox

Begin by updating your Linux Mint system. This step is crucial as it ensures that all your existing packages are current, which helps prevent any conflicts during the Waterfox installation.

Execute the update process with this command:

sudo apt update

Following the update, it’s advisable to upgrade any packages that are outdated. This can be done using the command:

sudo apt upgrade

This step maintains your system’s stability and security, making it ready for new software installations.

Step 2: Install Required Packages for Waterfox

Certain dependencies are required for a smooth installation of Waterfox. These dependencies, or packages, might already be present on your system. However, to confirm their installation, or to install any that are missing, use the following command:

sudo apt install software-properties-common apt-transport-https curl -y

Should you face any installation issues later, it’s a good practice to revisit this step to ensure all necessary packages are installed.

Step 3: Import Waterfox GPG Key

The next step involves importing the Waterfox GPG key. This is an important security measure, as it verifies the authenticity of the packages you are about to install. Depending on your version of Linux Mint, the command to import the key varies.

For Linux Mint 21 users, use this command:

curl -fsSL | sudo gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_hawkeye116477_waterfox.gpg > /dev/null

For those on Linux Mint 20, the command is slightly different:

curl -fsSL | sudo gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_hawkeye116477_waterfox.gpg > /dev/null

Step 4: Import Waterfox APT Repository

The final preparatory step is to import the Waterfox APT repository. This is similar to the previous step, but instead of importing the GPG key, you are importing the repository itself. Ensure you use the correct command for your specific Linux Mint version.

For Linux Mint 21:

echo 'deb /' | sudo tee /etc/apt/sources.list.d/home:hawkeye116477:waterfox.list

For Linux Mint 20:

echo 'deb /' | sudo tee /etc/apt/sources.list.d/home:hawkeye116477:waterfox.list

After importing the repository, finalize the setup by updating your package lists with the newly added repository:

sudo apt update

This command syncs your system with the Waterfox repository, making the software available for installation.
