Title: ISO Creation on a Docker-Enabled Ubuntu System: OverlayFS Error

Hi everyone,

I’m encountering an issue when trying to create an ISO of my Ubuntu machine that has Docker installed. During the process, I repeatedly get the error: “OverlayFS missing ‘lowerdir’”, which disrupts the CLI output. I suspect this might be related to Docker’s layered filesystem, but I’m not entirely sure.

Has anyone successfully created an ISO from a system running Docker, or faced a similar issue? I’m curious if this approach is even feasible, and would appreciate any insights or workaround suggestions.

Thanks in advance!

As the error message says, the filesystem is not supported. You can’t use overlay2 filesystem on an iso on which there is a special filesystem, but I don’t remember which one.
