Hello again, Dave! Looking at the logs, it doesn't seem that your problem is related to bug 1969162.
What I'm left to suspect is a storage issue, since there are many errors about files failing to load in the logs. I've had similar issues with a RPi3, where I had to flash the same Ubuntu image over the SD card a couple of times before the boot succeeded. Would you mind trying the same?
That is, just reflash the image a couple of times, and only afterwards you try booting.
