1、备份原文件mv /etc/apt/sources.list /etc/apt/sources.list.old

2、写入新源，以下是 Debian 11 的：

cat > /etc/apt/sources.list << EOF
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free
 
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free
 
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free
 
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security/ bullseye-security main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security/ bullseye-security main contrib non-free
EOF

如果是 Debian 12：

cat > /etc/apt/sources.list << EOF
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware
EOF

注：
deb 指向的是编译好的二进制软件包。
deb-src 指向的是软件的源代码包，可以使用apt source命令下载软件的源代码并自行编译。

重大通知！用户您好，以下内容请务必知晓！
由于CentOS官方已全面停止维护CentOS Linux项目，公告指出 CentOS 7和8在2024年6月30日停止技术服务支持，详情见CentOS官方公告。
导致CentOS系统源已全面失效，比如安装宝塔等等会出现网络不可达等报错，解决方案是更换系统源。输入以下命令：

bash <(curl -sSL https://linuxmirrors.cn/main.sh)

然后选择中国科技大学或者清华大学，一直按回车不要选Y。源更换完成后，即可正常安装软件。
