## how to remove hassio and supervisor
It's been a while since this gist was written. In the meantime the package homeassistant-supervised apt
package was introduced for debian based systems. If you used that way the first thing you should do use
the normal package uninstaller with something like: (sudo) apt remove homeassistant-supervised
If for some reason that doesn't work proceed with the below instructions for a manual cleanup.

1) stop services:
sudo systemctl stop hassio-supervisor.service
sudo systemctl stop hassio-apparmor.service

2) disable services:
	local:
	hostname -I optional with \| awk '{print $1}'
	ip addr show (ip a)
	ifconfig -a
	ip route get 1.2.3.4 \| awk '{print $7}'
	nmcli -p device show

	remote:
	curl or wget -qO- <host>
	hosts:
	check the timestamp files for the various apt components:
