I'm having trouble running Docker on my server. I've attempted to install it on several distributions, including Debian 12 and 13, as well as three different versions of Ubuntu. Despite being logged in as root and other users—who are all added to the Docker group—I'm getting an error whenever I try to run the hello-world container or any other containers. The error message states: "docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: open sysctl net.ipv4.ip_unprivileged_port_start file: reopen fd 8: permission denied: unknown." I've successfully run Docker previously on many Debian and Ubuntu servers, so I'm a bit puzzled. Can anyone provide insights or solutions?

You mentioned you have multiple servers running Docker smoothly, but this particular one isn't cooperating, right? Can you give us more details about how you set up this server? It sounds like you might be encountering an issue specific to the way it's provisioned. Also, double-check that you're not inadvertently setting it up within a container when you're trying to run it directly on the server.
There seems to be a recent issue with the containerd version that was released today. I managed to resolve it by downgrading to the last version available: containerd.io=1.7.28-1. If you haven’t tried downgrading yet, it could be worth a shot!
I had a similar issue recently, and the only fix for me was to restore my entire system from a backup. It started acting up after an update to containerd. After rolling back to version 5:28.5.1, my Docker was back to normal. You might want to try downgrading the Docker components to see if that solves the problem.
Are you running this on a VM or LXC? If it's LXC, that could be affecting Docker's ability to create containers properly. Just something to verify.
