APT(Advanced Packaging Tool) is a set of tools for managing Debian packages, and therefore the applications installed on your Debian system. APT makes it possible to: Install applications Remove applications Keep your applications up to date and much more... APT是一个客户/服务器系统。在服务器上先复制所有DEB包（DEB是Debian软件包格式的文件扩展名），然后用APT的分析工具（genbasedir）根据每个DEB包的包头（Header）信息对所有的DEB包进行分析，并将该分析结果记录在一个文件中，这个文件称为DEB索引清单，APT服务器的DEB索引清单置于base文件夹内。一旦APT 服务器内的DEB有所变动，一定要使用genbasedir产生新的DEB索引清单。客户端在进行安装或升级时先要查询DEB索引清单，从而可以获知所有具有依赖关系的软件包，并一同下载到客户端以便安装。 当客户端需要安装、升级或删除某个软件包时，客户端计算机取得DEB索引清单压缩文件后，会将其解压置放于/var/state/apt/lists/
