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 given 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 -
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
If Installation error like me, add the signing key

Reinstall again after adding the signing key
