如果你不是企业订阅用户务必删除企业订阅源，否则会造成依赖库无法正常安装等情况
以下命令适合新手不知道哪个源的情况下使用，直接删除其他的源：
rm -rf /etc/apt/sources.list.d/*下一步就是要更换你需要的第三方源，可以使用自带的vi编辑器或者nano编辑/etc/apt/sources.list，这里推荐使用nano，相对于该系统中的vi更好用：
nano /etc/apt/sources.list可以直接使用Back键删除，清空内容后复制下方的国内源直接覆盖即可
新手如何保存？
使用 CTRL+X组合键 ，根据提示是否保存发送 yes 接下来会提示是否覆盖，直接按enter回车默认即可
最后可以通过 cat /etc/apt/sources.list 验证是否更改成功
