[Bug 1863145] Re: arm64 cloud image contains flash-kernel which leads to apt errors on upgrade

[Robert C Jennings]

I have a questionable recreate and maybe Stephan Fabel can confirm if
this is what he's seeing.

I have launched an arm64 VM on AWS and on that VM I have started an 18.04 container from the 'ubuntu:' remote.  The container has a build serial of 20190307.  
Running 'apt update; apt upgrade -y' from this older image is enough to find an update for flash-kernel (3.98ubuntu11~18.04.1).  During the upgrade I see the following message:
  flash-kernel: /boot/vmlinuz- or /boot/initrd.img- missing; expecting future run
But the exit code from the upgrade is 0 and there are no broken packages.

Stephan, is this the extent of the failure that you have seen?  I was
going to help validate the fix from Dave but I want to ensure I'm seeing
the same failure first.
