sudo curl -sL -o /etc/apt/trusted.gpg.d/morph027-signal-cli.asc https://packaging.gitlab.io/signal-cli/gpg.key

echo "deb https://packaging.gitlab.io/signal-cli signalcli main" | sudo tee /etc/apt/sources.list.d/morph027-signal-cli.list

You will either need signal-cli-jre or signal-cli-native before you can use signal-cli-service/signal-cli-dbus-service.

Both packages are co-installable and the active one can be selected using sudo update-alternatives --config signal-cli.

sudo apt-get install signal-cli-<jre|native> morph027-keyring

sudo apt-get install signal-cli-service

sudo apt-get install signal-cli-dbus-service
