我一直在尝试在Ubuntu 9.04上安装kubuntu-kde4-desktop软件包，这给了KDE一定的帮助。我还没有完成它，但是如果我决定返回我尝试过的，真正喜欢的Gnome设置，我如何轻松地删除KDE东西而不必跟踪Synaptic中的所有组件？
我了解到kubuntu-kde4-desktop是一个元软件包，可作为完整KDE桌面体验所需的所有软件包的指针，因此，我认为我不能简单地做到这一点：
$ sudo apt-get remove kubuntu-kde4-desktop
如果我决定不以一种简单的命令方式使用它，该如何删除它们？
更新：我在这里添加了与此问题相反的内容。
Answers:
$ sudo apt-get remove kubuntu-kde4-desktop
$ sudo apt-get autoremove
将删除所有它拉到依赖的软件包。Alteratively，如果你使用aptitude像这样
$ sudo aptitude remove kubuntu-kde4-desktop
它将自动为您删除所有依赖包。就我个人而言，我更喜欢手动控制apt-get，它会告诉您何时有可以下次使用的软件包可以自动删除。
aptitude purge ~c在~c寻找aptitude的发现被删除的，但不清除任何软件包。因此，您在这种状态下正在清除任何东西。记住进行清理是一个很好的命令。
sudo apt-get --purge remove kubuntu-kde4-desktop
应该执行完全删除。
--purge新增了删除不再使用的软件包的配置文件的功能。但是正如TRS-80所指出的那样，autoremove此后应使用该命令来消除不必要的依赖关系。
kubuntu-kde4-desktop软件包本身没有配置文件，因为它是一个元软件包。而autoremove在第二个命令将不会对所有的自动删除的包清除配置文件。我个人发现，处理残留配置的最简单方法是忽略它们，除非它们妨碍了它们，然后使用Synaptic定期清除它们。
正如其他人指出的那样，您可以将apt-get与--purge remove和autoremove / autoclean选项一起使用。
您还可以使用deborphan命令（一个单独的程序包）来识别孤立的程序包，并删除已识别的程序包，以便：
sudo apt-get --purge remove `deborphan`
一个更全面的程序是debfoster（除草不必要的Debian软件包），我经常运行它来保持系统整洁。关于debfoster的一个相当古老的HOWTO向您展示了如何使用仍然相关的说明摆脱所有 KDE软件包。
运行中的一小段debfoster代码（我最近用它清除了系统中的日食和相关软件包）。请注意，您可以将一个包作为参数传递给它。
我会定期尝试并丢弃软件，而debfoster对于确保我将有害软件包的膨胀降至最低程度非常有用。
$ sudo debfoster
