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' ...
