Tried updating to latest but it broke my install

Hi guys,

I just tried to update my RPi 3 to the latest available update (0.51.1) and it never came back up.

And now when I ssh in to my box, I can’t even run docker commands to restart the container or anything. I fact most commands are not found.

the only clue I have to what went wrong is this.
2017-08-21 21:57:16 ERROR (MainThread) [homeassistant.components.hassio] Client timeout error on api request homeassistant/update.

Does anyone have any suggestions on how to recover from this? I can still backup my configs etc if I need to blow it away and start again but I was hoping it wouldn’t come to that.
