Debian 10 更换国内源 (中科大、网易源、阿里云)

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

2. 直接用此文件覆盖掉源

请依次执行：

1. 下载设置好的源文件
2. 覆盖现有源
3. 更新软件列表并更新软件

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

文件内容与上面代码内容相同
