mmfile.d:147 fails: Could not map file into memmory (Invalid argument)

Using ISO in qemu.

moss 0.1-2

When trying to install python:

I tried installing moss-dbginfo for better stack trace, but it didn't help (and `moss-dbginfo is at different version). I could not find debug package for other dependencies like phobos easily either).

Similar issue with zsh 5.9-1 package.

And ldc 1.30.0-1

And ruby 3.1.3-1 (initially it started install, but then got stuck. ctrl-c, and retry now leads to same issue as above)

python, ldc, ruby all have libffi in common, so maybe it is related

Lack of networking is the root cause - we need to add proper error handling.
