Headless without IP address>
I have installed both 16.04 and 18.04 on two different cards. How does one go about making a "headless" connection to this device if there is no IP address assigned to the network interface? I had to connect monitor and keyboard to access the boards. Looking in /etc/network/interfaces.d/etho I see that the card is set to manual. I looked in /etc/network/interfaces and there is no address set for the card. Why is the image called 'headless' if it requires a keyboard and monitor? On the 18.04 install it uses netplan. Same thing with its config -NIC is set to manual without a specified IP address.
