After the annoying MacM3 issues, I have found an old intel machine. It's running a Debian live distro on a 1TB ssd. Now I am stuck on step 12/20. Thoughts?

I run the repair command and rebuild the container, but yet again got the same message with some other ID's

I also deleted docker and ue4-docker and reinstalled it.

Is there any chance it's moby/buildkit#3965 (see also moby/buildkit#3898).

That's the only immediately-findable BuildKit issues I could find for that error message, and I guess it's possible that the ShaderCompileWorker build step created a UNIX socket, causing the WORKDIR step to fail.

There's a very short repro case at the top of moby/buildkit#3965 which should be able to verify that, and then per moby/buildkit#3898 it might be as simple as changing the Docker config to use overlay2, although that should be the default already...

Either way, it might help for further investigation to log the output of docker info.
