    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
