'''Advanced package tool''', or '''APT''', is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian, and Debian-based Linux distributions.

APT is a management system for software packages. Originally written for Debian and the deb package format, APT was ported and became APT-RPM to manage the rpm(8) package format. APT-RPM can be used by any RPM-based distribution, such as Conectiva, Red Hat, SUSE, ALT-Linux, etc.



apt 是一个命令行包管理器，用来搜索和管理以及查询有关包的信息。

它提供与专用 APT 工具（apt-get 和 apt-cache）相同的功能，但更好用

=== 更新可用软件包列表 ===
<syntaxhighlight lang="shell-session">
root@aade5ae73079:/var/www/html# apt update
</syntaxhighlight>

=== 配置 APT 源 镜像 ===
备份旧的源配置文件<syntaxhighlight lang="shell-session">
root@5033aa3ffae0:/etc/apt# cp sources.list sources.list.bak
root@5033aa3ffae0:/etc/apt# rm sources.list
root@5033aa3ffae0:/etc/apt# vim sources.list 
</syntaxhighlight>替换默认的 archive.ubuntu.com 为 mirrors.aliyun.com

参考 [[Ubuntu 配置镜像]]
