Debian分區系統更新主要包括軟件包更新和分區維護，步驟如下：
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt install unattended-upgrades
sudo dpkg-reconfigure unattended-upgrades
df -h # 查看磁盤使用情況
sudo lvextend -L +10G /dev/mapper/vg-root # 擴展邏輯卷
sudo resize2fs /dev/mapper/vg-root # 調整文件系統
sudo fsck -fy /dev/sda1 # 替換為實際分區
dd if=/dev/sda1 of=/path/backup.img bs=4Mdd if=/path/backup.img of=/dev/sda1 bs=4M/etc/apt/sources.list后執行apt update。參考來源：
