我知道StackOverflow上已经提出了这个问题，但我对提供的答案不满意。

一切正常，没有任何问题完全无人值守安装。
但是在安装系统步骤中，它开始从Internet进行安全更新，即使我在preseed.cfg文件中提到没有自动更新与d-i pkgsel/update-policy select none
并且在linux-image-3.14.0.34通用步骤失败了，因为我的设置中由于缺少Internet而没有从http://security.ubuntu.com获取该包。
如何解决该错误并继续操作而不会使此错误完全无人参与安装。
注意：我已尝试过的preseed.cfg和ks.cfg文件中注释的选项，但没有任何效果。
提前非常感谢你。
答案 0 :(得分：1)
d-i pkgsel/update-policy select none
在安装的pkgsel阶段工作，现在尝试取消注释
d-i apt-setup/security-updates boolean false
另请注意您的preseed.cfg包含
d-i pkgsel/update-policy select none
不止一次
