Setting up UC20 according to instructions on an RPi4. I have a serial connection and WiFi. I setup the wifi password, I enter my email address and it downloads my keys. After reboot, it comes back with:
Ubuntu Core 20 on (ttyS0)
You cannot log in until the system has an IP address. (Is there
supposed to be a DHCP server running on your network?)
I re-imaged three times. One time I added a static IP. Same result.
Here’s more of the log:
