apt-get的基於Debian和Ubuntu泊塢窗圖像失敗

Question

我在嘗試運行一個Debian或Ubuntu泊塢窗圖像apt-get的更新時，這個奇怪的錯誤：

E: Some index files failed to download. They have been ignored, or old ones used instead. 

我查了一下網址不存在，它應該是.gz或.bz2來代替。它只發生在一臺主機服務器上（運行Ubuntu），在boot2docker和Debian中工作良好。

Answer 1

我發現這是由於我們在將端口80重定向到localhost端口5000的服務器上設置的IP表規則。它是在兩個方向上意外設置的。

apt-get請求的URL沒有.gz/.bz2，因爲它已經失敗了。

Answer 2

由於您的實例的網絡問題，您收到Failed to fetch錯誤。它最有可能是高速緩存代理或壞鏡子。解決此問題的最簡單方法是使用VPN連接從其他地理位置獲取軟件包更新，這將觸發不同的鏡像。
