How to Install Signal on Ubuntu 22.04

Signal is a secure messaging and voice chat application. It’s primarily used on mobile phones, and will require a phone number to register, but it can also be installed on PC operating systems such as Ubuntu Linux. It works similarly to WhatsApp and Telegram but has a much bigger focus on user privacy and security.

In this tutorial, you will learn how to install Signal on Ubuntu 22.04 using GUI, snap, or apt package.

Installing Signal

To install Signal using the GUI method, all you have to do is open up the Ubuntu Software application, then search for “Signal” and install the one listed as signal-desktop.

Step 1. Firstly, we have to import the GPG key from Signal.

Step 3. Finally, install Signal.
