关于如何诊断问题，有什么指示吗？
答案1
总而言之，问题似乎出在网络启动服务器的基本操作系统上 —— 它太旧了。
最好使用 Ubuntu16 服务器来托管网络启动映像。
或者尝试此解决方法，因为您无法安装其他软件包（使用 apt-get），因为网络启动镜像中缺少 i18n 目录。此脚本添加缺少的 i18n 目录并从 Ubuntu 存储库获取文件。此脚本应在 apt-mirror 之后运行。
/var/www/postmirror.sh：
#!/bin/bash
## anything in this file gets run AFTER the mirror has been run
## put your custom post mirror operations in here ( like rsyncing the installer files and running clean.sh automaticly )
## Example of grabbing the extra translations and installer files from ubuntu ( note rsync needs to be installed
## and in the path for this example to work correctly )
# NOTE: This script should be run as root
