Hello all! I'll up this topic.
I have Libreelec installed to AM1 (x86-64) base, on SSD. It works greate!
I am able to run docker containers. Now it runs Portainer (port:9000).
There are no any problems to run HA Container.
But i've got same problem to run Hass.io install script.
While reading install scrip i understnend, that there are no requests to any impossible thins listed in it.
Two container image are downloaded. Two binary application too.
Service (systemd) is possible to run it (enable and start), relocation needed.
I have some troubles, that i can't understand, and suppose that it need smallest step to get hassio completely working.
Excuse me, for my bad English.
