Cannot run hello-world after upgrade

Docker Engine General
1

Hi all; hope you can assist. Last night I finally did an update of Immich which is the only app I run under Docker on a Ubuntu machine. That upgrade seemed to go okay and confirmed I could talk to the Immich server afterward. Then I decided to do an apt update and apt upgrade; which seemed to work fine until it got to Docker, then it got stuck.
After multiple reboots and killing off the Immich server images; I seemed to get the Docker to upgrade. But then Immich wouldn’t start. Eventually I checked and realized that even Hello-world wouldn’t start. It just locks up.

I’ve tried reinstalling the docker components. Doesn’t seem to make a difference.

Here’s the Docker version output.

Please, show how you run the hello world container mentioned in the title. I’m not sure how immich is relevant when the problem is with running “hello-world”. If anything runs automatically not directly executing Docker commands, try the docker commands so see if it is a Docker issue or some kind of compatibility issue between Docker and another application.

When you share how you ran the hello-world container and what the error message, is, please, use MarkDown to format the command and the output. (3 backticks before and after the code block: How to format your forum posts) Or use the </> button above the message composer.

Hope this helps… this was right after a reboot.

So; the first time, it complains… the second time, it just stopped and looked at me stupidly (had to break out of it).

Oh; and noticed that there were three new logs in the Docker status:

Here is a rather old issue that has some suggestions on how to fix the issue:

In my case, it’s 100% consistent. I can’t run any container, it seems. It was pointed out that I’m running ubuntu 20.*, is that old enough that Docker would have issues?

I have an old vm with Ubuntu 20 and the same docker engine version: this is not the reason it’s not running.
Ubuntu 20.04 and Docker 28.1.1 are EOL and have no support whatsoever.

It must be a configuration you applied to the system. Could be the result of “hardening” the system.

Did you try the suggestions from the GitHub issue I shared?
