On casaos/rpi, the port 53 is occupied by docker-proxy process and not systems. Hence the commands wont work, I'm afraid to kill docker-proxy, what if it takes down casaos? Any expert please help
$ sudo netstat -tulpn | grep ":53 "
tcp 0 0 0.0.0.0:53 0.0.0.0:* LISTEN 1152/docker-proxy

I can't deactivate the port, it gives me this error when launching the last command
ash-4.4# sudo systemctl stop systemd-resolved.service
Failed to stop systemd-resolved.service: Unit systemd-resolved.service not loaded. ¿?
