install home assistant on x86 docker

You just need to look at the source:

Generic x86-64

Install Home Assistant on Generic x86-64 systems (e.g. Intel NUC)

www.home-assistant.io

(I think the name of the docker image is wrong and you should replace 'http://ghcr.io/home-assistant/home-assistant:stable' with 'homeassistant/home-assistant' as it appears on https://forum.libreelec.tv, check this yourself)

Very important warning: Before installing a new docker Home Assistant container, remove the previous ones installed. If you don't know docker, study a little starting here https://docs.docker.com/
