Home Assistant Supervised Update to Debian 11 and New Supervisor.

Update to Debian 11

(steps from Debian 10)

Based on what I did today, I threw this together. The supervisor itself does not appear to be released as of the time of this document, but I wanted to get out there what I have in case it helps anyone.

I am currently running Debian 11 with os-agent humming but the old version of the supervisor. It is complaining unsupported as the OS version is wrong… All appears to be working functionally

Back-up everything you do not want to loose to another device. I only worried about my Ha install, so I pulled a back-up snapshot and got it onto another drive using Ikifar’s backup tool. Make sure you have a good back-up. (Check it if necessary) I am not responsible for you losing data.

Then update your existing packages and reboot your system, then check the update again until nothing needs updating.
Update command: sudo apt-get update; sudo apt-get upgrade -y

Edit the file /etc/apt/sources.list using a text editor and replace each instance of buster with bullseye. Next find the security line, replace keyword buster/updates with bullseye-security. Mine looked like this when I was done: Mileage may vary. Back-up the file before editing it. More info here

Update the system again. You may see an error regarding public key signatures. If so I suggest looking here for a fix– public-key-is-not-available sudo apt-get update; sudo apt-get upgrade -y It should list around 500 file changes including some questions you will need to answer. I chose to install the suggested version in my cases. Mileage may vary.

Update the distribution: sudo apt full-upgrade

reboot the system

Update the system again.
sudo apt-get update; sudo apt-get upgrade -y

Get the os-agent program

Download the correct file for your system. Files are located at (https://github.com/home-assistant/os-agent/releases/latest) For Debian 11 currently it is this, but get the latest rev: os-agent_1.1.1_linux_x86_64.deb

Install dependencies: apt-get install udisks2 libglib2.0-bin -y

Install os-agent: sudo dpkg -i os-agent_1.1.1_linux_x86_64.deb

                  (Filename has to match the file downloaded.)

You can test if the installation was successful by running: gdbus introspect --system --dest io.hass.os --object-path /io/hass/os

You should get a response with the matching revision listed towards the bottom.

Docker environment variables

Check that your Docker Environment variables are installed correctly: docker inspect hassio_supervisor|grep Env -A10

You should see these lines somewhere, if not edit the file and put them there. Back-up the file before editing it.

                "SUPERVISOR_SHARE=/usr/share/hassio",
                "SUPERVISOR_NAME=hassio_supervisor",
                "SUPERVISOR_MACHINE=qemux86-64",
