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!

Signal ubuntu setup

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 | sudo apt-key add -
echo "deb [arch=amd64] 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

That’s it!

I love computers; maybe way too much. What I learned I try to share at


  1. md5sum: /etc/apparmor.d/usr.lib.snapd.snap-confine: No such file or directory
    snapd.failure.service is a disabled or a static unit, not starting it.
    snapd.snap-repair.service is a disabled or a static unit, not starting it.
    I received this message, on my ubuntu 16.04 LTS machine. Installation of signal progressed fine, so I am prone to believe this is not critical

  2. *****19.10 Ubuntu******
    Had issues installing Signal-Desktop after a fresh install of the OS. Root cause of the issue is related to the fact that Signal Desktop requires YARN to be installed first. Steps below:
    # All commands from the Terminal as Sudo
    sudo apt install cmdtest
    # optional command to verify yarn install
    yarn –version
    # another optional command if curl is not already installed
    sudo apt install curl
    # add the signal source to the local keyring
    curl -s | sudo apt-key add –
    # verify the distribution being referenced for installation
    echo “deb [arch=amd64] xenial main” | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
    # refresh the repositories and install signal
    sudo apt update && sudo apt install signal-desktop

  3. The first method worked beautifully I’ve been trying to get this installed on my Chromebook for months thank you

  4. what the fuck? I just want to make a call from my desktop, not link to my phone..
