为什么apt-get无法解析镜像？
可能重复：
apt-get update无法获取文件，“临时故障解决…”错误
我知道这已经被覆盖过，但我似乎无法解决我的问题。 这是我的输出。

我有同样的错误。 我最初认为这是/etc/apt/sources.list中的一个错误，但是在ping了不仅是security.ubuntu.com以及google.com ，我发现我的服务器连接到网络但没有到达外面网络。
我编辑了/etc/network/interfaces并将eth0设置为DHCP而不是静态。 然后我让我的路由器负责为服务器提供静态IP。 重启服务器，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您的问题背后的周围情况。
如果它说，您似乎有一些包管理问题，可能是由于您正在使用的镜像，可能缺少或需要更新您要求的Precise包。
试试这个：
-
打开终端并输入：
sudo nano /etc/apt/sources.list编辑源文件。
-
在开始时，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这应该告诉
apt-get根据你的地理位置自动为你挑选一面镜子。 -
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。
