aptitude 是 Debian GNU/Linux 系统中, 非常神奇的的软件包管理器,基于大名鼎鼎的 APT 机制, 整合了 dselect 和 apt-get的所有功能, 并提供的更多特性,特别是在依赖关系处理上。
aptitude与 apt-get 一样，是 Debian 及其衍生系统中功能极其强大的包管理工具。与 apt-get 不同的是，aptitude在处理依赖问题上更佳一些。举例来说，aptitude在删除一个包时，会同时删除本身所依赖的包。这样，系统中不会残留无用的包，整个系统更为干净。
以下是一些常用 aptitude命令，仅供参考。
命令作用
aptitude update 更新可用的包列表
aptitude upgrade 升级可用的包
aptitude dist-upgrade 将系统升级到新的发行版
aptitude install pkgname 安装包
aptitude remove pkgname 删除包
aptitude purge pkgname 删除包及其配置文件
aptitude search string 搜索包
aptitude show pkgname 显示包的详细信息
aptitude clean 删除下载的包文件
aptitude autoclean 仅删除过期的包文件

这个？

我的理解：
upgrade等同于safe-upgrade，dist-upgrade等同于full-upgrade，

引用:

Note
This command was originally named dist-upgrade for historical
reasons, and aptitude still recognizes dist-upgrade as a
synonym for full-upgrade.

所以主要是safe和full的区别：

引用:

safe-upgrade
Upgrades installed packages to their most recent version. Installed
packages will not be removed unless they are unused
……
It is sometimes necessary to remove one package in order to upgrade
another; this command is not able to upgrade packages in such
situations. Use the full-upgrade command to upgrade as many
packages as possible.

引用:

full-upgrade
Upgrades installed packages to their most recent version, removing
or installing packages as necessary. This command is less
conservative than safe-upgrade and thus more likely to perform
unwanted actions. However, it is capable of upgrading packages that
safe-upgrade cannot upgrade.
