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:
sudo systemctl disable hassio-supervisor.service
sudo systemctl disable hassio-apparmor.service

3) remove services:
sudo rm -rf /etc/systemd/system/hassio-supervisor.service
sudo rm -rf /etc/systemd/system/hassio-apparmor.service

4) removing folders:
sudo rm -rf /usr/sbin/hassio-supervisor
sudo rm -rf /usr/sbin/hassio-apparmor

5) remove containers/images

hello thanks,

works for me except the number (5), i got this
remove: not found

Yeah, that's not a command, just a general sentence.
To remove all stopped containers use:
docker container prune
To list the images (because there might be ones you want to keep), do:
docker images
then remove the ones you want with:
docker rmi < Image ID>

ohh i get it...

sudo docker container rm container-ID1 container-ID2........ container-IDn

thanks!!!

thanks, useful thread

apt remove homeassistant-supervised
Then remove containers and images

@forzagreen That's specific to the homeassistant-supervisor.deb installation. That works if you are on debian and used this specific installer.

thank you for this!
