Ubuntu 12.04国内最新最快的源地址

我们有时在升级Ubuntu时，发现源特别的慢，尤其中cn.archive.ubuntu.com:80 (123.129.214.98)这个源，电信根本无法连上，一天也升不了级。是因为这个源是联通的线路，电信非常慢。在国内，也有别的更新很快的源，比如和网易和搜狐。我们下面以网易为例。

网易镜像源地址：http://mirrors.163.com。5小时更新一次，同步还是比较快的，速度也不错。

Ubuntu下更改源地址，输入sudo gedit /etc/apt/sources.list，全部删除，再换上新的源即可，各种源如下。更新源前请务必备份原始的源。
