Ubuntu 16.10 server - cant get HA to install

sudo apt-get install python3-pip

sudo pip3 install homeassistant

both ran fine it appears

(error - You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the ‘pip install --upgrade pip’ command.)

after starting hass

sudo ~/.local/bin/hass

http://192.168.1.200:8123 is unreachable, but i do not see any errors

No errors in the console? Can you see that hass is starting up in the console?
Are port 8123 in your router open?

I had an issue as well. Went ahead and upgraded pip and then installed/ran homeserver - now it comes up.

Just run hass as your user (not root). That should populate/start properly then.
