Ubuntu16.04 替换阿里云软件源

Ubuntu16.04 替换阿里云软件源

一，首先为源文件做备份

1，进入源文件 sources.list 所在的目录：

cd /etc/apt/

2，对源文件进行备份

执行命令：

sudo cp sources.list sources.list.bak

二，修改源文件 sources.list 里的内容

1，复制以下阿里云软件源文件内容：

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

如要用于其他版本，把 xenial 换成版本代号就好：

ubuntu16.04 - xenial ubuntu15.10 - willyubuntu14.04 - trustyubuntu12.04 - precise

2，打开 sources.list 文件，并删除里面所有内容
打开文件：

sudo vi sources.list

将复制的内容粘贴到本文件中

最后： 输入:wq保存退出！

三，更新源和软件

sudo apt-get update
