The following guide will demonstrate how to install Seamonkey on Debian 12 Bookworm, Debian 11 Bullseye, or Debian 10 Buster using the Ubuntuzilla apt third-party repository for the latest version and for easy future updates using CLI commands.

Section 1: Install SeaMonkey Internet Suite

Step 1: Update Debian Linux

Begin by updating your Debian system to ensure you have the latest packages installed. Run the following command:

sudo apt update && sudo apt upgrade

This command first updates the package list (with apt update) and then upgrades all installed packages to their latest versions (with apt upgrade).

Step 2: Import GPG Key

Install Required Packages

Before importing the GPG key, install the necessary packages by running:

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

These packages will allow you to manage GPG keys and repositories securely.

Create GPG Directories (if necessary)

If you have not previously imported a GPG key from the Ubuntu keyserver, you may need to create the necessary directories. Run the following command:

sudo gpg --list-keys

Or for root users:

gpg --list-keys

Example output:

gpg: directory '/root/.gnupg' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: /root/.gnupg/trustdb.gpg: trustdb created

This command lists the GPG keys and creates the required directories if they don’t exist.

Import the GPG Key

Next, import the GPG key required to verify the authenticity of the packages:

sudo gpg --no-default-keyring --keyring /usr/share/keyrings/ubuntuzilla.gpg --keyserver --recv-keys 2667CA5C

This command imports the Ubuntuzilla GPG key into a custom keyring file (/usr/share/keyrings/ubuntuzilla.gpg) from the specified keyserver.

Example output:

gpg: keybox '/usr/share/keyrings/ubuntuzilla.gpg' created
gpg: key B7B9C16F2667CA5C: public key "Daniel Folkinshteyn (Ubuntuzilla signing key) <>" imported
gpg: Total number processed: 1
gpg:               imported: 1

Step 3: Add Ubuntuzilla Repository

With the GPG key imported, you can now add the Ubuntuzilla repository to your system:

printf 'deb [signed-by=/usr/share/keyrings/ubuntuzilla.gpg] all main\n' | sudo tee /etc/apt/sources.list.d/ubuntuzilla.list

This command creates a new repository file (/etc/apt/sources.list.d/ubuntuzilla.list) containing the Ubuntuzilla repository information and specifies that the repository is signed with the previously imported GPG key.

Step 4: Update Package List

Update the package list again to include the newly added Ubuntuzilla repository:

sudo apt update

Step 5: Install SeaMonkey Internet Suite

With the repository added and package list updated, you can now install the SeaMonkey Internet Suite:

sudo apt install seamonkey-mozilla-build

This command installs the latest version of SeaMonkey from the Ubuntuzilla repository.

Section 2: Launch SeaMonkey Internet Suite

After installing the SeaMonkey Internet Suite, you can launch it using one of two methods: through the command line interface (CLI) or via the graphical user interface (GUI) of your Debian system. Both methods are explained below.
