为什么apt-get无法解析镜像？

Question

可能重复：
apt-get 更新无法获取文件，“临时失败解决……”错误

我知道这之前已经涵盖过，但我似乎无法解决我的问题。这是我的输出。

任何帮助是极大的赞赏。

Answer 1

我有同样的错误。我本来以为它是一个错误/etc/apt/sources.list，但做了之后ping不仅security.ubuntu.com但是google.com还有，我发现，我的服务器是连接到网络，但没有达到外网。

我编辑/etc/network/interfaces并设置eth0为DHCP而不是静态。然后我让我的路由器负责为服务器提供一个静态 IP。重新启动服务器，一切正常。

您可以在此处找到有关 IP 配置的更多信息。

您没有详细说明可能解释问题背后原因的周围情况。

据说，您似乎遇到了一些包管理问题，可能是由于您正在使用的镜像而导致，该镜像可能丢失或需要更新Precise您所请求的包。

尝试这个：

1. 打开终端并输入：

   sudo nano /etc/apt/sources.list
   

   编辑您的源文件。

2. 在最开始，添加以下行：

   deb mirror://mirrors.ubuntu.com/mirrors.txt precise main restricted universe multiverse
   deb mirror://mirrors.ubuntu.com/mirrors.txt precise-updates main restricted universe multiverse
   deb mirror://mirrors.ubuntu.com/mirrors.txt precise-backports main restricted universe multiverse
   deb mirror://mirrors.ubuntu.com/mirrors.txt precise-security main restricted universe multiverse
   

   这应该会告诉apt-get您根据您的地理位置自动为您选择镜子。

3. 保存文件并更新您的来源：

   sudo apt-get update
   

这假设您没有遇到任何互联网连接或 DNS 问题。

希望这可以帮助。
