linux改变apt-get安装源，linux改变apt-get

最近自己装了个ubuntu kylin 在使用的过程中发现，系统的apt-get 的源有毛病，总是安装不了软件。

感觉应该是传说中的墙的原因，所以准备换到阿里云的源。

下面是步骤：

1、复制原文件备份

sudo cp /etc/apt/source.list /etc/apt/source.list.bak

2、编辑源列表文件

sudo vim /etc/apt/source.list

3、将原来的列表删除，添加如下内容

deb http://mirrors.aliyun.com/ubuntu/ vivid main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ vivid-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ vivid-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ vivid-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ vivid-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ vivid main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ vivid-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ vivid-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ vivid-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ vivid-backports main restricted universe multiverse

4、运行sudo apt-get update

5、运行sudo apt-get upgrade

以上就完成了对源的更换。
