使用工具 xen-create-image 时，我遇到了 debootstrap 过程错误。

所以我尝试运行：
chroot /tmp/ubuntu dpkg --force-depends --install /var/cache/apt/archives/debconf_1.5.42ubuntu1_all.deb
交互地。

输出：非法指令（核心转储）似乎暗示 debconf 存在一些基本问题。有没有办法解决这个问题，以便我可以让 debootstrap 脚本无错误地运行？
答案1
尝试
apt-get install dialog
找到了这里遇到同样的问题后。（我遇到过debootstrap wheezy --variant=minbase）
或者，您可以使用
export DEBIAN_FRONTEND=noninteractive
运行之前apt-get。这将回退到纯文本控制台界面，该界面也适用于脚本或 Dockerfile。
答案2
到目前为止，我遇到过两次同样的问题，这是由一个混乱的软件包引起的。在终端中运行以下命令应该可以解决问题：
apt-get update && apt-get dist-upgrade
