Hello, after typing the commands pi@raspberry:~$ sudo systemctl enable nodered.service
it replied as such:- Failed to enable unit: this file nodered.service does not exist
Can you run this command again?
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
It looks like your Node-RED installation might have failed. Let me know if this command works for you, then run this command again:
sudo systemctl enable nodered.service
