Now, let’s dive into the specifics of installing SeaMonkey on your Ubuntu system.

Install SeaMonkey on Ubuntu via APT PPA

Update Ubuntu Before SeaMonkey Installation

Before proceeding with the tutorial, ensuring your system is up-to-date with all existing packages is good.

sudo apt update

Proceed to upgrade any outdated packages using the following command.

sudo apt upgrade

Install Initial Packages For SeaMonkey

The first and easiest method is installing SeaMonkey using the source APT repository from UbuntuZilla to quickly keep up with any new changes. Another great feature is the repository works for all currently released Ubuntu versions that are not EOL.

First, install the required packages.

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

Import GPG Key For SeaMonkey

For users who have not previously imported a GPG key from the Ubuntu keyserver, the command line terminal will often have issues importing GPG keys from LaunchPAD PPAs because the directories are not created. This is an easy fix. Use the following command that will, in turn, generate the directories.

This can be skipped, but run the command and re-try if you encounter an issue.

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

Now, import the APT repository using the following command.

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

Run a quick APT update to reflect the newly added APT source.
