Как исправить эту ошибку с помощью debootstrap в Ubuntu Server 12.04.3?

При использовании инструмента xen-create-image я получаю сообщение об ошибке с процессом debootstrap.

Запуск

root@xen/tmp# debootstrap --arch amd64 precise /tmp/ubuntu

W: Failure trying to run: chroot /tmp/ubuntu dpkg --force-depends --install /var/cache/apt/archives/debconf_1.5.42ubuntu1_all.deb

Итак, я попытался запустить:

chroot / tmp / ubuntu dpkg --force-зависимость --install / var / cache / apt / archives / debconf_1.5.42ubuntu1_all.deb

Интерактивно.

root@xen:/# chroot /tmp/ubuntu dpkg --force-depends --install /var/cache/apt/archives/debconf_1.5.42ubuntu1_all.deb

Вывод: недопустимая инструкция (ядро сброшено) Кажется, подразумевает некоторую фундаментальную проблему с debconf или чем-то еще. Есть ли способ обойти эту проблему, чтобы я мог запустить скрипт debootstrap без ошибок?
