Ubuntu 配置阿里云源

如何换成国内最快的阿里云源

第一步：备份源文件

cd /etc/apt/

然后会显示下面的源文件 sources.list
输入命令

sudo cp sources.list sources.list.bak

将 sources.list 备份到 sources.list.bak

第二步：替换源文件

阿里云源

    deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse  
    ##测试版源  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse  
    # 源码

    # Canonical 合作伙伴和附加
