This looks like python version issue. Are you able to pin pint what component triggers it? or at which stage of startup this error shows up?
Do you notice something not updating or failing (too) fast (I guess the issue is related with .sleep(n) and just does not wait)?

So how do you start HA?
Try to start it by entering hass in a terminal.

[olskar]

I get it very early, about 15 seconds into the start of hass. No matter if I use it or not. I run hassbian so I Think it starts with /srv/homeassistant/bin/hass?

I am getting this same error running AIO .56.2 on Raspbian Stretch

[ferdydek]

vaguely related to aio-libs/aiohttp#2098
but I think without complete run logs we will not go further with this error.
