1. 找到并备份配置文件sources.list

我们需要对apt源的配置文件进行修改 。进入/etc/apt目录,我们可以看到sources.list文件。

为了保证安全,我们在修改前先把sources.list文件进行备份

$ sudo cp sources.list sources.list.bak

2. 修改配置文件sources.list

建议先安装vim编辑工具,因为自带的vi特别难用,vim是vi的增强版。

$ sudo apt-get install vim

vi或者vim操作sources.list文件,先清空原有的内容(官方源)。然后再把下面的阿里源复制进去。
