Following the instructions on “Autostart using systemd” I have created a daemon using nano to restart Home Assistant. On completing the daemon As per the instructions I pressed “Control x “ to exit and then “y” the save it. The nano screen did not close down and I don’t know why. All the my searches indicate that I have done the right thing. I’ve tried Control z to no avail. I don’t want to power off my raspberry as I’ll have to go the process of restarting again. Is there any other way to get out of nano. Any ideas?
