更新時 ftp debian 儲存庫失敗

我有一個在 Vagrant 中執行的 ubuntu 16.04 伺服器。當我執行時，apt-get update我收到以下錯誤：

我已經嘗試了很多解決方案，但我無法解決它，知道發生了什麼嗎？您需要更多數據嗎？

貌似ftp.es.debian.org目前下架了。您可以替換http://ftp.es.debian.org/debian/您sources.list的http://deb.debian.org/debian/哪個應該自動選擇一個工作鏡像。確保apt-get update之後執行。

您需要從您的 : 中刪除 debian 儲存庫sources.list：

sudo sed -i '/debian/d' /etc/apt/sources.list
sudo apt update
