Ubuntu 服務器 14.04 安裝的 PXE 設置會產生問題

Question

我知道 StackOverflow 上已經有人問過這個問題，但我對所提供的答案並不滿意。

PXE 使用我的 kickstart 文件的一部分

我的設置：

• Ubuntu 桌面 14.04 LTS (x86) 與 PXE (TFTP + Apache) 設置。

• 掛載 Ubuntu 服務器映像 14.04.2 並使用ks.cfg和preseed.cfg創建完全無人值守的安裝

ks.cfg 的配置：

一切正常，沒有任何問題，完全無人值守安裝。

但是在安裝系統步驟期間，它開始從 Internet 進行安全更新，即使我在 preseed.cfg 文件中提到沒有使用di pkgsel/update-policy select none自動更新di pkgsel/update-policy select none

並在 linux-image-3.14.0.34-generic 步驟失敗，因為由於我的設置中缺少 Internet，它沒有從http://security.ubuntu.com獲取該包。

如何解決該錯誤並繼續而不會完全無人值守安裝時出現此錯誤。

注意：我已經嘗試並測試過preseed.cfg和ks.cfg文件中注釋的選項，但沒有任何效果。

非常感謝你。

Answer 1

d-i pkgsel/update-policy select none

在安裝的 pkgsel 階段工作現在嘗試取消注釋

d-i  apt-setup/security-updates      boolean false

另請參閱您的 preseed.cfg 包括

d-i pkgsel/update-policy select none

不止一次
