Reproduce for this issue is as simple as downloading -root.tar.xz (or
-root.tar.gz) from http://cloud-images.ubuntu.com/daily/server/xenial ,
then extracting it, chrooting and apt-get installing a kernel.

I believe that amd64 works fine, so to see failure you have to either
use qemu-user-static or actually run on the correct arch.

# if running non-native arch, use qemu-user-static
sudo apt-get install -qy qemu-user-static
wget http://cloud-images.ubuntu.com/daily/server/xenial/current/xenial-server-cloudimg-arm64-root.tar.xz

exdir=$(mktemp -d)
mkdir "$exdir"
sudo tar -C "$exdir" -xSpf xenial-server-cloudimg-arm64-root.tar.xz

# fix resolv.conf for dns to your local system's settings
sudo mv "$exdir/etc/resolv.conf" "${exdir}/etc/resolv.conf.dist"
sudo cp /etc/resolv.conf "$exdir/etc/resolv.conf"

# if cross, patch in qemu-user-static
sudo cp /usr/bin/qemu-aarch64-static "$exdir/usr/bin/"
sudo chroot "$exdir" sh -exc 'apt-get update && apt-get install -qy linux-generic'
