APT 换源解决拉取慢

换源后更新的命令：

apt update -y         #更新索引
apt full-upgrade -y        #更新软件
apt dist-upgrade -y    #升级
apt clean -y          #删除缓存包
apt autoclean -y       #删除未安装的deb包

Debian

使用 HTTPS 、强制使用非自由软件源、强制安全更新使用镜像几个选项都要开

针对 Debian GNU/Linux12 (bookworm) ：

vim /etc/apt/sources.list

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
