I have Raspberry Pi (model B plus v1.2) and configure as headless system with VNC. When I start the node red, I found this message as follow:
sudo: unable to resolve host RPiBPlusv12: Name or service not known
Please refer to attached photo for more detail.
I'm not sure about the message is an error or warning. But I can use Node Red as usual.
And the message is coming again if I use "sudo systemctl enable nodered.service" as follow:
Is it problem with that message?
