无法安装 openssh 服务器 
sudo apt-get install openssh-server

我收到此错误：

Err mirror://mirrors.ubuntu.com/mirrors.txt/ precise-updates/main openssh-server i386 1:5.9p1-5ubuntu1.4

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

我的/etc/apt/sources.list内容是：

deb mirror://mirrors.ubuntu.com/mirrors.txt precise main restricted universe
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

为何以及怎样解决它？

我认为您的问题可能与这个错误有关：https://bugs.launchpad.net/ubuntu/+source/apt-cacher-ng/+bug/1020995。我也尝试在 Ubuntu 14.04 上使用镜像功能，但出现了一些错误。

您可以备份 /etc/apt/sources.list 文件

sudo mv /etc/apt/sources.list /etc/apt/sources.list.orig

并创建一个新的，内容如下。替换ro.archive.ubuntu.com带有您所在国家/地区的首字母（例如 fr、de、us 等）。
