Comment 1 for bug 1806813

Hi David, can you add your voice to bug 1805668 please? I expect the beta image you are using uses the updated packages described in that bug report.

I have no experience of the compute module, but I expect changes similar to https://wiki.ubuntu.com/ARM/RaspberryPi#Booting_the_official_Pi_2_image_on_the_Pi_3B.2F3B.2B- will make the image bootable. For arm64 you need to make an additional change https://wiki.ubuntu.com/ARM/RaspberryPi#Ubuntu_arm64.2FAArch64 . Once booted I suggest you remove either the raspi3-firmware or flash-kernel package as they are both trying to do the same job.
