Debian 12更换apt源

因为要配置使用https的源，这需要先确保安装证书认证工具：

sudo apt install ca-certificates -y

编辑系统文件/etc/apt/sources.list，其中阿里云源如下：

deb https://mirrors.aliyun.com/debian/ bookworm main non-free non-free-firmware contrib
deb-src https://mirrors.aliyun.com/debian/ bookworm main non-free non-free-firmware contrib

deb https://mirrors.aliyun.com/debian-security/ bookworm-security main
deb-src https://mirrors.aliyun.com/debian-security/ bookworm-security main

deb https://mirrors.aliyun.com/debian/ bookworm-updates main non-free non-free-firmware contrib
deb-src https://mirrors.aliyun.com/debian/ bookworm-updates main non-free non-free-firmware contrib

deb https://mirrors.aliyun.com/debian/ bookworm-backports main non-free non-free-firmware contrib
deb-src https://mirrors.aliyun.com/debian/ bookworm-backports main non-free non-free-firmware contrib

使用sudo apt update更新源。
