This idiot can't get idiot-proof Hassbian started - asyncfilters.py?

After futzing with HA and OZWCP on various Ubuntu and Raspbian boxes, I had varying degrees of success, but too much was broken or clumsy for satisfaction. So I tried the all-singing, all-dancing image recommended here: (URL) home-assistant.io/docs/hassbian/installation/

I figured this + RPI3 = mindless success for basic functionality without the glitches caused by my inexperienced piecemeal stumbling. No such luck.
