I spent the last 24 hours pretty much trying to get Docker installed and running. I tried installing from the terminal using the Docker documentation, and tried installing from within webmin and spent hours on Docker discord with their support. Nothing seems to work.
I am assuming plenty of people must have Docker working with Ubuntu 22.04 and virtualmin/webmin. The Docker support pretty much told me to just uninstall and not use webmin which was not much help.
Webmin has nothing to do with Docker. I mean, there is absolutely nothing Webmin does that would interact with Docker.
I have to assume that if you followed the exact same process without Webmin installed, you’d get the exact same result.
That said, I’ve never had problems with Docker on Ubuntu 20.04 (my other job is currently locked on 20.04 across our infrastructure, so I haven’t used it on 22.04). (And, Webmin being installed or not makes no difference.)
Yea, I agree with you. I tried to tell Docker support that but they were super focused on the fact i had Webmin installed.
I just really need to get Docker installed and working or I am screwed. This is a fresh install of Ubuntu 22.04 with only webmin/virtualmin on it and now Docker.
If you can help me at all try to troubleshoot this it would be a blessing. The Journalctl does not say much to me.

I can’t do anything with that. There is no useful error there. I’m no Docker expert, but if you post the actual errors from the journal, I might have suggestions.
Er, I guess that is the journal, but I still don’t see any useful errors. I’d try starting the docker daemon manually using whatever command the systemd unit is running to see what the actual errors are.
I don’t know much about docker install on Ubuntu but if I was you I would do a fresh install and try a docker install by itself so to get use to installing docker.
I’m not sure what resources you have. But if that works ok then install VM. Still all good. Backup you VM and restore to new machine.
Then you messed something up along the way. I’ve done it and it runs perfectly.
As Joe mentioned, it has absolutely nothing to do with Webmin/Virtualmin. You need to work in Ubuntu terminal only. DO NOT use the terminal via Webmin/Virtualmin. Use the terminal directly in Ubuntu.
I installed Docker (and uninstalled it) around 10 different times from the terminal before trying it in Webmin because I was so frustrated that I can not get it to work.
If you have installed it on ubuntu 22.04 and it works perfectly maybe you can help me? Which install method did you use? Obviously, something is messed up but when nearly an 8-hour day was wasted installing and uninstalling and Docker support discord and here can not get any info from the errors it is hard to figure out what to do next.
You do realize that lists 4 different ways to install it, right?
I installed it using the “Install Using the Apt Repository” method. I certainly hope you didn’t run every command listed in that article. If you did, you’ve got a complete mess going.
I also used the same install method over 10 times. Every single time it installs fine up until the point you see on the screenshot and then the errors begin.
Every install is easy when it works perfectly, the issue is when it does not and how to figure out why. From the Docker discord support to this forum, no one can figure out what is causing this so far.
Webmin does not install a firewall. Virtualmin does.
I’m not sure, though, why Docker would have a problem interacting with local services, regardless of the firewall. The firewall only effects incoming network activity, nothing with local services. I can’t think of any legitimate reason Docker would conflict with a firewall that does not do anything to local communications (i.e. 127.0.0.1 is not touched by the firewall).
I would love to understand more myself. All I know is as soon as I stopped firewalld everything went smoothly with the installation of docker. Someone in the Docker discord suggested i try it.
Keep this in your notes for the next time you need to install docker on Ubuntu 22 server.
I have over 12 VPS with Docker and Firewalld with Webmin for management.
The only ports you need to open in the firewall are ports the docker app needs to talk to the outside world.
