每天凌晨3点自动同步UBUNTU源

根据挂载的不同版本（ubuntu22/ubuntu24)的本地源调整mirror.list配置

#!/bin/bash
# /root/run-apt-mirror.sh

mount /dev/sda1 /var/spool/apt-mirror/
if mountpoint -q /var/spool/apt-mirror; then
        if find /var/spool/apt-mirror/ -maxdepth 5 | grep noble 2>&1 > /dev/null; then
                cp /etc/apt/mirror.list.24 /etc/apt/mirror.list
        else
                cp /etc/apt/mirror.list.22 /etc/apt/mirror.list
        fi
    /usr/bin/apt-mirror > /var/spool/apt-mirror/var/cron.log 2>&1
else
    logger -t apt-mirror-cron "错误：/var/spool/apt-mirror 未挂载，任务跳过。"
    exit 1
fi
