ubuntu系统 apt-get 安装不了软件
运行提示：
huzd@ubuntu:~$ sudo apt-get install subversion
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package subversion
先sudo apt-get update，也是一样。
执行这个命令时，有些包取不下来，提示：

换源,,,,
[解决办法]
ping这个地址延迟很高、还丢包。换源。

163网易的源很好的样子，以前用10.04的时候换，后来11.10用的默认的了
