我正在尝试使用 cobbler pxeboot 并安装 Ubuntu 18.04.6，每次我选择 Ubuntu-18.04.6-hwe 时都会出现此情况（见屏幕截图），它总是退出到选择国家/地区位置。 pxeboot 截图
我找不到这样做的原因。我尝试了几种方法来解决这个问题，但似乎都没有用。有人能帮忙吗？这是预置文件：
### Preseed for Ubuntu 18.04
# Derived from: https://help.ubuntu.com/lts/installation-guide/example-preseed.txt
### Usage
# We recommend to use the build-iso.sh script to build an image with embedded
# preseed and other required files. In that case the preseed file gets loaded
# automatically and all additional files are available to the installer.
