It is definitely not supposed to fail like that, and did not do so
when I tested it.  Failing to migrate is not a fatal error.  The code
in question look like this:

        if [ -f $flagfile ] ; then
            # Still using legacy ordering, try to convert
            if try_to_convert ; then
                :
            else
                echo "error: Unable to migrate to dependency based boot sequencing."
            fi
        fi

There is nothing there exiting with an error code.

Can you try to add 'set -x' at the start of
/var/lib/dpkg/info/sysv-rc.postinst and let me know what is printed
when you try to configure the sysv-rc package again?

Happy hacking,
