The Signal is a free, cross-platform, open-source communication app that’s simple, fast, and secure. Its main goal is protecting users’ privacy.
So, if you’re looking for a highly secure, privacy-first communication client that works on desktop and mobile devices, Signal may be something you want.
Besides just chatting and instant messages, users can use Signal to make crystal-clear voice and video call across town or long distances. Signal messages and calls are always end-to-end encrypted and engineered to keep users’ communication safe.
When you’re ready to install Signal, continue with the steps below.
Below are two options available when installing Signal on Ubuntu desktops…. You can select either one to get it installed…
Install Signal DEB Package
To install Signal using its DEB package, go to the link below and select the Linux install option. From there, you should see installation instructions and commands to get it installed. The commands are simple. Just copy and paste, and you’re all set!
Run these commands to install Signal Desktop on Ubuntu desktops—to open the Ubuntu command line terminal, press Ctrl — Alt — T on your keyboard.
sudo apt install curl curl -s https://updates.signal.org/desktop/apt/keys.asc | sudo apt-key add - echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list sudo apt update && sudo apt install signal-desktop
After running the commands above, Signal should be installed and ready to use. Although the package repository looks like it’s for Xenial, it should also work on Ubuntu 17.10 and 18.04. So ignore the name for now and install it.
To launch it, go to the Activities Overview, search Signal, and launch it. When you first launch the app on Ubuntu, you’re prompted to link to your Signal Desktop.
Install Signal via Snap
The Signal can also be installed via Ubuntu snap package management… This might be the quickest way to install Signal.
Snap is a universal package manager that enables users to install and maintain packages on Ubuntu systems quickly… However, Ubuntu 16.04 and the previous version may not have Snap installed by default… so run the commands below to install.
sudo apt install snapd sudo snap install signal-desktop
