config-host: file not found

Your host may not be using bash for /bin/sh which is probably a symlink to some shell other than bash. The last time I heard about this, it was fixed on a Fedora host system by changing the first line of the shell scripts in the _scripts/ directory. They all have something like

     #!/bin/sh -eu

on the first line. Change it to

     #!/bin/bash

You might need to make the scripts writable with "chmod 755 <file>.sh".
