Hassio installation broke completly overnight

Dear all,

I am running Ubuntu 20.04.4 LTS desktop. Hassio has been installed as a docker installation for the past 3 years and worked like a charm. I have ~50 devices and integrations connected.

This morning (~5 hours ago), I noticed that none of my MQTT devices were working. I did some troubleshooting, all devices (mostly TASMOTA devices) are still conncected via Wifi to my Odroid H2, and can be triggered via their own IP adress. Naturally, I rebooted my server.

Now, hass.io does not even start. The whole hass.io system is gone. On the same server, there is also a nextcloud-installation running, which I can use without any problems whatsoever. The problem is thus not related to my internet, my Wifi, or anything else in my network.

When I type “systemctl status docker” I get this:

It seems like the docker installation did not even start. I did NOT manually update anything, nor did I change a thing on my server. This completly happened on its own. There seems to be some breaking changes related to docker-installs as far as the --init command goes in the latest update:

I am, however, a complete dummy when it comes to docker. Can anybody walk me through on how to fix this?

Thanks you very much!

You can try running the installation package again - won’t lost anything and won’t do any harm but may fix the problem

I solved it via google:

If anybody wonders.

docker -v showed version 19. I upgraded to version 20 as mentioned in the thread above via using this:

Thanks for reading though!
