清除更新索引
apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y
命令講解：
apt-get clean //清除緩存索引
apt-get update //更新索引文件
apt-get upgrade //更新實際的軟件包文件
apt-get dist-upgrade //根據依賴關系更新
檢查更新
apt update
更新
apt upgrade 如果軟件包有相依性問題，此軟件包就不會被升級
apt dist-upgrade 如果軟件包有想依性問題，會移除舊版本，直接安裝新版本（有點風險）
