以Ubuntu16.04为例

操作步骤

1 备份原来的源文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bcakup

2 编辑源文件

编辑器打开源文件

sudo vi /etc/apt/sources.list

清空后输入以下内容

# 阿里云源

deb [http://mirrors.aliyun.com/ubuntu/](http://mirrors.aliyun.com/ubuntu/) xenial main restricted universe multiverse

deb [http://mirrors.aliyun.com/ubuntu/](http://mirrors.aliyun.com/ubuntu/) xenial-security main restricted universe multiverse

deb [http://mirrors.aliyun.com/ubuntu/](http://mirrors.aliyun.com/ubuntu/) xenial-updates main restricted universe multiverse

deb [http://mirrors.aliyun.com/ubuntu/](http://mirrors.aliyun.com/ubuntu/) xenial-backports main restricted universe multiverse

##測試版源

3 执行更新

保存退出后执行以下命令

sudo apt update

其他Ubuntu版本

1 查看版本号

执行lsb_release -a查看codename，对应的就是相应的版本号，不同版本号需要将以上文本内容“xenial”对应修改
例如，版本号为“bionic”的版本，文本内容为:

# 阿里云源

deb [http://mirrors.aliyun.com/ubuntu/](http://mirrors.aliyun.com/ubuntu/) bionic main restricted universe multiverse

deb [http://mirrors.aliyun.com/ubuntu/](http://mirrors.aliyun.com/ubuntu/) bionic-security main restricted universe multiverse
