update:
All docker images of hassio addons were gone. After clicking ‘start’ for each addon in Supervisor the exact name of the missing image was displayed, which I manually downloaded with docker image pull <name>
I got things working on the latest version of docker-ce now.
What I did is restart hass a couple of times using # hassio-supervisor start / stop / status. After a few attempts hass started. Then i restored a snapshot.
It takes some waiting in between, bus after about half an hour things are running again
Downgrading docker-ce package to 5.19 version solved the problem for me.
After that I only had to re download the docker images of the hassio addons I use.
I have been pulling my hairs since last midnight… I always blamed it to new supervisor requirements when i am on ubuntu 18.04 on Intel NUC. I even updated to Ubuntu 20.04. Now i find this, went back to docker 5.19; everything is fine. Thanks a lot guys, you are the best…
You are really great guys. Had the problems with Debian buster since yesterday and did not know how to fix this. But the downupgrade to docker 5.19 worked.
Ran across this thread and stranger yet, running official Docker-ce I noticed that current version is 19.03 again now with a subversion of 3-0 for the officially supported Debian config.
My HA has been horribly unstable with both Supervisor and all Docker stuff crashing outright for a couple of days.
Restored to VM backup just to get it running this morning. Console wouldn’t even run “ha” saying the container wasn’t responding.
Attempting to look at logs I would sometimes see supervisor complaining that one of the core Docker IP addresses had stopped responding three times and then nothing and the box was completely dead.
Okay, I ran into a problem with the TasmoAdmin add-on. It won’t start, but it also won’t report to me the name of the image with the image error. It also won’t uninstall.
How can I manually override this and wipe it out so I can re-install it?
