I re-etched the SD card with my windows laptop, just to be sure, and let the Pi run all night. Same problem. I also tried booting the Pi without the SSD, same problem.
Then I put the RPi OS back on the SD card. It comes up fine. Then I re-etched again the Umbrel OS onto the SD card. I plugged my keyboard and mouse into different USB ports and this time I was able to log in. On the terminal I see only a command line, and I was able to log in with umbrel/umbrel. However, I still get the endless series of port messages as shown in the screen shot.
Still “no route to host” when using the IP address that the router shows the Pi connected to.
Bleh, it might be this. DeskPi Pro v2 Case - fan doesn't work But the script way of installing Umbrel isn’t ready yet for 1.0.x… “Coming in April 2024”…
