To upgrade outdated packages, use this command.

Install Initial Packages For SeaMonkey

One simple way to install SeaMonkey is by using the source APT repository from UbuntuZilla, which ensures you stay updated with the latest changes. Additionally, the repository is compatible with all active Ubuntu versions that haven't reached end-of-life.

Begin by installing the necessary packages.

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

Import GPG Key For SeaMonkey

New users who haven't imported a GPG key from the Ubuntu keyserver might face issues when importing GPG keys from LaunchPAD PPAs due to missing directories. To resolve this easily, generate the necessary directories with the following command.

While this step is optional, run the command if you encounter any problems and then retry.

sudo gpg --list-keys

Example output:

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

Next, import the GPG key.

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

Example output:

/usr/share/keyrings/ubuntuzilla.gpg --keyserver keyserver.ubuntu.com --recv-keys 2667CA5C
gpg: keybox '/usr/share/keyrings/ubuntuzilla.gpg' created
gpg: key B7B9C16F2667CA5C: public key "Daniel Folkinshteyn (Ubuntuzilla signing key) <nanotube@users.sourceforge.net>" imported
gpg: Total number processed: 1
gpg:               imported: 1

Import UbuntuZilla PPA For SeaMonkey

Next, use the following command to import the APT repository.

printf 'deb [signed-by=/usr/share/keyrings/ubuntuzilla.gpg] https://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main\n' | sudo tee /etc/apt/sources.list.d/ubuntuzilla.list >/dev/null

Perform a quick APT update to incorporate the newly added APT source.

sudo apt update

Finalize SeaMonkey Installation via APT Command

Finally, install SeaMonkey by executing the following command.

sudo apt install seamonkey-mozilla-build

Launch SeaMonkey on Ubuntu via CLI or GUI

CLI Command to Launch SeaMonkey

With the SeaMonkey internet suite installed, launch the application immediately by entering the following command in your terminal:

GUI Path to Launch SeaMonkey

Another way to launch the software suite is by navigating to its icon through the application path.

Activities > Show Applications > SeaMonkey

Additional SeaMonkey Commands

Update SeaMonkey

Use the following terminal commands to check for updates. These will comprehensively check all installed packages on your system to align with the package manager. Running this is recommended, even if auto-updates are enabled, to ensure your system is current and to prevent update errors, especially for newer users.

sudo apt update && sudo apt upgrade

Remove SeaMonkey

For those who no longer want SeaMonkey installed, remove the internet suite using the following command.

sudo apt install seamonkey-mozilla-build --purge

It's a good housekeeping and security practice for users who won't use the APT import repository again to remove it safely.

sudo rm /etc/apt/sources.list.d/ubuntuzilla.list

Additionally, you can remove the GPG key using the following command.

sudo rm /usr/share/keyrings/ubuntuzilla.gpg
