Install Signal Messaging Desktop on Ubuntu

Every knows that WhatsApp changes its End Users License Agreement (EULA) . Lots of people are worried about data privacy.

That is why I’m migrating to Signal Messaging. I installed Signal Desktop on Ubuntu but I faced small hiccup which I shared how to solve it.

Download Signal for desktop

Download it here: https://signal.org/en/download/#

and follow the givenĀ  instructions.

Can get the signing key from the error messageInstall Signal official public software signing key

wget -O- https://updates.signal.org/desktop/apt/keys.asc |\
  sudo apt-key add -
signal desktop install ubuntu - signing key
signal desktop install ubuntu – signing key

Add Signal repository to your list of repositories

echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" |\
  sudo tee -a /etc/apt/sources.list.d/signal-xenial.list

Update Ubuntu package database and install signal

sudo apt update && sudo apt install signal-desktop
signal desktop installation ubuntu - error during installation
signal desktop installation ubuntu – error during installation

If Installation error like me, add the signing key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [signing key]

//example
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32

Can get the signing key from the error message

signal desktop install on ubuntu getting the signing key
signal desktop install on ubuntu getting the signing key

Then run the command

signal desktop installation ubuntu - add key
signal desktop installation ubuntu – add key

Reinstall again after adding the signing key

signal desktop installation ubuntu successful
signal desktop installation ubuntu successful

 

Reference:

Fix apt-get update “the following signatures couldn’t be verified because the public key is not available”
