环境： Ubuntu 24.04.1 LTS
使用时的安装命令是

 curl -sS https://installer.cloudpanel.io/ce/v2/install.sh -o install.sh; echo "2aefee646f988877a31198e0d84ed30e2ef7a454857b606608a1f0b8eb6ec6b6 install.sh" | sha256sum -c && sudo DB_ENGINE=MARIADB_10.11 bash install.sh

卸载主程序和相关附加软件包、依赖

sudo rm -rf /var/lib/dpkg/info/cloudpanel* && sudo apt remove cloudpanel -y && sudo apt purge cloudpanel -y && sudo apt autoremove -y

检查空间 df -h，发现应该还是没删干净，检索关键字
经过 updatedb && locate -i cloudpanel 检查，还有些残留
清理残留

rm -rf /home/clp

rm -rf /usr/share/doc/cloudpanel

rm -rf /var/crash/cloudpanel*

rm -rf /etc/sudoers.d/cloudpanel /etc/mysql/ /etc/apt/trusted.gpg.d/cloudpanel-keyring.gpg /etc/apt/preferences.d/00packages.cloudpanel.io.pref

多释放了 1.5 GiB，所有附带安装的软件包及其生成的配置文件被处理干净了，收工
