Never use --force-all.  It is very dangerous and is entirely capable of
accidentally trashing large swathes of your filesystem when a less
cavalier set of options would have produced a sensible error messages.
All the reasonable things you might want to force have much safer

Is there any reason not to bind-mount /proc into your chroot?  We don't
support running very much without /proc in place, and certainly not
installing packages in general.
