I often share a template that mentions “code block” and even shows an example, which I didn’t do in this case, so I admit it was not clear what I was referring to. On the other hand, basically every technical forum uses markdown-based code blocks to make sure the output is shared as it appeared in the terminal, so I don’t always feel the need of an example 
And you can see I was in a hurry, since I had a lot of typos in my message.
No problem with that, just leave a small note that this is the case and we can either help with the formatting or just accept the comment as is if it doesn’t make a huge difference, like in your case. But shared terminal outputs often make the forum post unreadable or some part of the message could be hidden the way markdown interprets it and only moderators would have a way to see that when they edit your post. Which means fewer people who are able to help.
Well, there is “dark net” which is usually used to describe something that should not be related to your issue. I immediately associated to that when reading “dark network”. I can imagine that some people use it for “air-gapped”, but I have never heard it in that context. If you can share a link that confirms that “dark network” is used to mean “air-gapped”, I would be glad to learn from you, since I often worked with air-gapped environments and never had this expression you used.
I’m sincerely sorry if my previous post seemed rude to you. It was not my intention, but I don’t believe your reaction is how you should handle these situations If you read other topics, you could probably see I can accept criticism and admit when I’m wrong, but helpers on forums can ignore questions or reply quickly so at least some conversation can be started and you won’t always see the most carefully expressed comments. On the other hand, a question has to be as well-expressed (and formatted) as possible, otherwise there will be much fewer people to try to understand it. And it is in your interest to attract more people.
Back to original topic:
I still shared what I could tell you about the issue. The docker info and version output was needed so we can see what kind of Docker you have exactly as people often don’t know the difference between the many kind and different builds. For example we often saw that someone used Podman and still asekd about it as Docker.
I still answer when I can even when it is not strictly about Docker, or not the official version (as we are a community forum, not an official Docker support, just people helping in their free time), but we mostly have exprience with the official Docker installed on officially supported operating systems, which does not include Alma Linux. So that is why I didn’t have a more detailed answer, not because I wouldn’t have been happy to write one. When I searched for the error message, I found what @bluepuma77 shared too, but I didn’t think it was your issue.
If your snapshot included all the data, not just the operating system, the only way to break Docker would be something network-related or a bug on Docker Hub, which would probably (not necessarily) affect other people, but I’m not aware of any issue that could cause this. If the docker data root was completely emptied as well, data coruption could not be the problem either. In some cases special or broken terminals can cause problems too. Or even remote Docker daemon connections.
Maybe there is some information missing which we don’t even think of at the moment and hopefully someone comes who will and ask for more details or clarification to solve it. Until then, you can share anything that comes to your mind related to the issue which you think could help someone to help you. You can also check the GitHub repo of Moby
Search for existing issues, comment if you think one is related or open a new one if you think it could be a bug not discussed yet.
