System Showing as an Unsupported Instillation. NUC/Ubuntu/Docker

[ThomYoung]

Hi folks,

I am hoping someone can help as I have been searching the site for ages looking for answer to this issue but I can’t even work out exactly what the issue is and I think I have only confused myself more.

Early 2019, I upgraded my set up from a Rasberry Pi to a NUC. I understood very little of what I was doing but thanks to several helpful guides on the net I was able to install Ubuntu, docker, Home Assistant Core and Portainer and I have managed to keep them all up to date and running fine ever since.

A few months ago I noticed that sometimes when I tried to update Home Assistant Core it wouldn’t and I got a message saying system was unhealthy. I did not know what this was but after rebooting the system it would then update with no problem. Recently I have a better understanding of where the issue might be. I noticed this:

When I clicked on learn more I got this:

I’ve read all the links and I am guessing it has something to do with the new OS agent? But then I am at a loss of how I fix that and if that even is the issue.
I also noticed it is showing as unsupported where that was not a problem before I am sure:

How do I fix this issue? I was thinking about uninstalling Home Assistant from docker and then reinstalling but due to my lack of knowledge I have struggled to work out how to uninstall and again I am not sure if that is the right thing to do. Can any one point me in the right direction please; felling a little lost?

The main issue is that you are running supervised on Ubuntu. This has has not been supported for more than a year.
Make a snapshot (now called backup), copy it off your nuc,

Either install Debian 11 :

Installing Home Assistant Supervised on Debian 11 This guide will help you to install Home Assistant Supervised, on almost any machine type you choose. This guide has been tested on machines including a Lenovo m72e, Dell Optiplex SFF 990, Dell Optiplex USFF 780 and a HP T520 thin client. Using Debian 11 and following a strict set of guidelines available HERE will give you a supported installation of Home Assistant Supervised. If you choose at anytime to install additional software to…

or install HA OS :

Generic x86-64

After installation, you can restore your backup (snapshot) and everything will work again.

Amazing! Thank you! I noticed that it talked about Debian and not Ubuntu and wondered if that was an issue but wasn’t sure if I was misunderstanding something. I looks like a process that will need a bit of time for me to get it right, so I will give it a go at the weekend.

Thank you again for your help.

A 3rd route is to turn your ubuntu (in the NUC box) into a VM server, and then run HA OS inside your VM.
Linux - Home Assistant (home-assistant.io)

Thank you. That’s great; it gives me another option.

So I ended up installing HA OS as I don’t intend to use using my NUC for anything else and it means I have fewer moving parts to look after, which works better for me. Followed instructions and all is back up and working well with no issues now.
