第一步、sudo  cp   /etc/apt/sources.list   /etc/apt/sources.list.bak 备份

  文件里内容大概是这样:

    Ubuntu18.04换源

 



 

第二步、修改源文件source.list

    1. 终端执行命令:sudo  chmod  777  /etc/apt/sources.list更改文件权限使其可编辑;
    2. 执行命令:sudo  gedit   /etc/apt/sources.list打开文件进行编辑;
    3. 删除原来的文件内容,复制下面的任意一个到其中并保存(常用的是阿里源和清华源,推荐阿里源);

  阿里源:
