Debian 10 更换国内源 (中科大、网易源、阿里云)

super

如有必要请在修改的覆盖的操作前做好备份, 下面内容可按需复制或抄写，比如我一般只用中科大源

1. 修改文件 /etc/apt/sources.list 为下面内容
下面内容中默认开启了中科大的源，请根据自己需求决定使用哪个源。 方法： 直接取消注释就好

1. # Debian 10 buster
   
2. 
   
3. # 中科大源

2. 直接用此文件覆盖掉源
请依次执行：

下载设置好的源文件
覆盖现有源
更新软件列表并更新软件

1. wget http://qiniu.xiwen.online/Debian10.list
   
2. sudo mv Debian10.list /etc/apt/sources.list
   
3. sudo apt update && sudo apt upgrade -y
