Please sync https://updates.signal.org/desktop/apt from debian xenial main

the advice on https://signal.org/download/ to install on deb based OS is not working in Kubuntu 18.04 Beta2 - maybe it can be in Discover?

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

signal is available via discover
