Running HA Supervised on an Ubuntu 20.04. I also have this problem for a while now. Since Supervisor updates itself automatically, with every new supervisor version this error comes up. My solution is, whenever i have this “Supervisor not Priviliged” written in Supervisor System page, i ssh into Ubuntu and:
sudo docker restart hassio_supervisor
And that solves the problem until the next automatic supervisor version update. As i see, whenever there is a new version, docker does not restart the container (that’s maybe it is a new container from a new image); so you have to do that yourself. I do not know how long this solution will last but we’ll see.
Although the administrators say “There is no support for unsupported systems like ubuntu supervised etc”, and close the issues on github without solution, i find them right in a way. They never guarantee that the system will work on an environment that they do not design it for.
However, on our defense, i also have other apps on this ubuntu system for other purposes. And the system works perfectly and i am planning to resist until the last moment not to use proxmox or hassos. That is not suitable for my situation, personally. And auto-updating of supervisor every time brings new surprises and problems together with it. Once my system is stable, i would like to keep the version intact and not update it unless i really need to because of a bug or a new item. So, for me, it is very normal to keep HA version 0.99 whatever if it is working stable. But unfortunately that is not the situation now. Of course i always have the option to work with HA core without supervisor; but i need config backup-restore and some addons desperately. If there was only a way to merge these two together… Anyway, i humbly and kindly request from the administrators to make supervisor updates optional. Thanks…
