Sorry for being unclear; I was suggesting to modify the image _before_ your
boot,

# on your arm64 host
1. wget
http://cloud-images.ubuntu.com/daily/server/bionic/current/bionic-server-cloudimg-arm64.img

2. sudo apt install cloud-image-utils
3. sudo mount-image-callback bionic-server-cloudimg-arm64.img -- chroot
_MOUNTPOINT_ /bin/bash

This drops you into a bash shell inside the cloud-image that's not yet
booted, from here you can
 set a root password with:

4. passwd

Then type 'exit' to leave the chroot, and then boot this modified image
along with your
cloud-config or anything else. Then you can login as root with the
password you set.
And collect some debugging data.
