无头安装:无法安装busybox-initramfs

Question

我正在尝试建立一个在一些盒子上安装Ubuntu的方法。这些机箱是从内部MMC存储器启动的x86机器。我希望该方法尽可能自动化，因为我们可能有大量的盒子来安装它；我的主要目标是使机器在安装后处于一致状态。我发现了这问题，但这两个答案都解决不了这个问题。

我使用一个预置文件来自动化安装步骤；安装似乎通过分区步骤工作，但是它失败了，出现了一个令人沮丧的模糊错误消息。以下是我认为相关的/var/log/syslog中的行：

Aug 25 17:46:07 base-installer: apt-install or in-target is already running, so you cannot run either of
Aug 25 17:46:07 base-installer: them again until the other instance finishes. You may be able to use
Aug 25 17:46:07 base-installer: 'chroot /target ...' instead.
Aug 25 17:46:07 in-target: Unexpected error; command not executed: 'sh -c debconf-apt-progress --no-progress --logstderr --     apt-get -q -y --no-remove install busybox-initramfs'
Aug 25 17:46:07 base-installer: error: exiting on error base-installer/kernel/failed-package-install

我使用的是USB驱动器上的预置文件，UbuntuServer16.04.3映像被写入它，并修改了文件isolinux/txt.cfg以使用我的预置文件。安装是成功的，当我做一个正常的安装，所以我相信这是一个问题的预置文件。

请注意，这些框不能访问internet；它们必须使用HTTP代理进行apt。我已经确认HTTP代理工作正常，并在预设文件中正确地指定了它。

我已经尝试重写ISO图像，这仍然会导致同样的错误.

我的预置文件有问题导致安装失败吗？

Answer 1

结果发现，syslog中还有另一个有趣的错误，我错过了：

Aug 25 21:03:12 live-installer: /usr/bin/ckbcomp: Can not find file "symbols/en" in any known directory
Aug 25 21:03:12 base-installer: warning: /usr/lib/post-base-installer.d/25live-installer-console-setup returned error code 1

这就是我修改后的txt.cfg的样子：

default my-installation
LABEL my-installation
  menu label ^my custom installation
  kernel /install/vmlinuz
  append  file=/cdrom/preseed/my-installation.seed debian-installer/locale=en_US locale=en_US console-setup/ask_detect=false keyboard-configuration/layoutcode=en console-setup/layoutcode=en netcfg/choose_interface=enp1s0 initrd=/install/initrd.gz ramdisk_size=16384 root=/dev/ram rw quiet

我从这应答中得到了“我们”指令(它是用来跳过键盘提示的)，但结果是它应该是'us'，而不是'en‘。更改这将导致ckbcomp命令成功，这将导致成功的系统安装。
