我正在使用 Ubuntu 發行版的本地鏡像，使用“apt-mirror”軟體包，當我# apt-get update在 14.04 系統上時，我看到“Ign”行。
在有鏡像的系統上，鏡像清單包含以下內容：（我沒有顯示 Lucid、Precise 等條目）
# Trusty/14.04LTS
deb-i386 http://us.archive.ubuntu.com/ubuntu trusty main restricted universe multiverse
deb-i386 http://us.archive.ubuntu.com/ubuntu trusty-security main restricted universe multiverse

deb-src http://us.archive.ubuntu.com/ubuntu trusty-security main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu trusty-updates main restricted universe multiverse
該apt-mirror命令已運行，並且 Trusty 鏡像清單的所有內容均已下載。系統透過 HTTP 呈現此儲存庫鏡像。在 14.04 系統上，我有一個來源清單檔案：

然而，當我運行時apt-get update，我收到幾行“Ign”。我知道這些本身不是錯誤，但我更願意「填充」鏡像來滿足這些錯誤，或者了解如何讓系統在不需要時停止尋找它們。

這是否意味著我缺少“inRelease”和“Translation-en_US”成分在我的鏡子裡？
我的理解是有“主要”、“受限”、“宇宙”和“多元宇宙”成分……所以這似乎不是問題。
我在 Debian wiki（某處）中讀到“inRelease”（與“Release”）與軟體包的簽名方式有關。
所以我想我的鏡子上有一些選項需要調整。
