Dependency problem upgrading to 0.93

When I try to upgrade homeassistant from 90.1 to 93.0 I get the following (Note, I upgraded libffi just fine using pip. HomeAssistant usually notifies me when there is and update, but evidently stopped after 90.1. I have not changed a thing, except adding the yaml code to my configuration.yaml):

(homeassistant) homeassistant@RaspberryPi:/ $ python3 -m pip install --upgrade homeassistant
