Install LibreWolf on Linux Mint 21 or 20 via APT

Step 1: Update Linux Mint Before LibreWolf Installation

Before installing LibreWolf, it’s crucial to update your Linux Mint system. This ensures compatibility and security.

Start by updating your package list:

sudo apt update

This command refreshes your system’s package list, checking for updates. Next, upgrade any outdated packages:

sudo apt upgrade

Upgrading ensures that all your system’s packages are current, reducing the risk of compatibility issues during the LibreWolf installation.

Step 2: Install Required Packages For LibreWolf Installation

LibreWolf requires specific dependencies to run correctly. While some may already be installed, executing the following command verifies and installs any missing ones:

sudo apt install curl dirmngr ca-certificates software-properties-common apt-transport-https -y

Skipping this step may lead to installation issues. If you encounter problems later, rerun this command to ensure all necessary dependencies are present.

Step 3: Import LibreWolf APT Repository and GPG Key

Secure installation involves verifying the authenticity of the LibreWolf packages.

Start by importing the GPG key:

curl -fsSL | sudo gpg --dearmor | sudo tee /usr/share/keyrings/librewolf.gpg > /dev/null

This command fetches and adds the official LibreWolf GPG key to your system, ensuring the integrity of the packages you download.

Next, add the LibreWolf repository:

echo deb [arch=amd64 signed-by=/usr/share/keyrings/librewolf.gpg] jammy main | sudo tee /etc/apt/sources.list.d/librewolf.list

This step involves adding the LibreWolf repository to your system’s sources list and making the software available for installation.

Step 4: Install LibreWolf via APT Command

After adding the repository, update your package list to include the new repository:

sudo apt update

This command refreshes the system’s package list, recognizing the newly added LibreWolf repository.

Finally, install LibreWolf:

sudo apt install librewolf

This command installs the LibreWolf browser on your Linux Mint system. Once the installation is completed, LibreWolf is ready for use.

Install LibreWolf on Linux Mint 21 or 20 via Flatpak with Flathub

Step 1: Verify Flatpak Installation

Before installing LibreWolf through Flatpak, confirm that Flatpak is installed on your Linux Mint. Flatpak is often pre-installed on Linux Mint, but it’s good to check its presence, especially if you have made system changes.

To verify Flatpak’s installation, execute:

flatpak --version

This command displays the installed Flatpak version, confirming its availability on your system. Flatpak is crucial for this process as it allows for isolated and secure installations of applications, including LibreWolf.

Step 2: Add or Enable the Flathub Repository

LibreWolf is available on Flathub, a major repository for Flatpak applications. Adding Flathub to your system expands your access to a variety of applications.

To add Flathub, use this command:

sudo flatpak remote-add --if-not-exists flathub

This command conditionally adds the Flathub repository, ensuring its presence for downloading LibreWolf. Flathub is a key resource for accessing the latest versions of numerous applications.

Step 3: Install LibreWolf via Flatpak Command

With Flatpak and Flathub set up, you’re ready to install LibreWolf. Execute the following command to install it via Flatpak:

flatpak install flathub io.gitlab.librewolf-community -y

This command initiates the installation of LibreWolf from the Flathub repository.
