You can disable signalk by:
sudo systemctl disable signalk.service
sudo systemctl disable signalk.socket
sudo reboot
If system restarts open a terminal
cd /usr/lib/node-module/signalk-server
npm start
Now it should show you the error.

Code:

pi@openplotter:~ $ sudo systemctl disable signalk.service
Removed /etc/systemd/system/multi-user.target.wants/signalk.service.
pi@openplotter:~ $ sudo systemctl disable signalk.socket
Removed /etc/systemd/system/sockets.target.wants/signalk.socket.
pi@openplotter:~ $ sudo reboot

and then:

Code:

pi@openplotter:~ $ cd /usr/lib/node-module/signalk-server
bash: cd: /usr/lib/node-module/signalk-server: No such file or directory
pi@openplotter:~ $ npm start
