I am seeing this also. I can deploy 18.04, but not 20.04. 20.04 fails with cloud-init Data Source Not Found Exception.
This is the second machine I’ve deployed and the first one deployed successfully using 20.04. They are configured almost identically although verifying the BIOS configs is a pain in the ass. Anyone know of any tools that can dump the BIOS config to a text file? Or did the ubuntu 20 image change in the last 4 days? Where are the images stored?
