I have had to search the armhf (I used pkgs.org for this) builds of these dependencies, but note that libmozjs185-dev depends on libmozjs185-1.0 which depends on libffi6.

Using Andbdrew's tips above I was able to make this work headless (and with a head) consistently without disabling Cloud-Init. Thanks to @enconn, for brainstorming and a link to https://cloudinit.readthedocs.io/en/latest/topics/examples.html#reboot-poweroff-when-finished.
