Sounds like the read only boot partition issue again. That update tries to update the kernel and modules, and will fail if the boot partition is read only.
Fortunately the January 2016 version has code that will help prevent this in the future, once it’s installed fully.
Here’s a thread that explains how to fix it, but for some less “Linux Skilled” people, the best option IMO is to wait until the new Jarvis installer image is available, and reinstall.
