我安装了kubuntu-desktop只是为了尝试其界面。然后，我决定删除并进行传统的apt-get清除和自动删除，但似乎kubuntu的元素仍然存在。例如，界面元素，滚动条，引导屏幕等仍然存在。
有什么方法可以在不安装ubuntu副本的情况下完全删除？
Answers:
我建议您使用aptitude来执行此操作，这将搜索将删除KDE环境并保留Ubuntu默认设置的软件包：
sudo apt-get install aptitude
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(ubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' ubuntu-desktop+
这将搜索任何kubuntu-desktop依赖于但不依赖于的软件包ubuntu-desktop。而且，这种方法有点贪婪。它将删除Qt程序包，ergo mplayer2，VLC，并且依赖于Qt库的所有程序包都可以删除。在末尾添加带有加号（+）的软件包，例如ubuntu-desktop软件包。对于其他口味：
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(xubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' xubuntu-desktop+
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(lubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' lubuntu-desktop+
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(ubuntu-gnome-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' ubuntu-gnome-desktop+
如您所见，仅将最后一个软件包名称替换为您首选离开的名称。如果使用过kde-core或其他中继包，则应使用中继包的名称替换“ kubuntu”。
为了确切说明选择哪个软件包，让我们更深入地说明搜索命令：
?and(
?and(
?and( // we're searching for packages that are
?reverse-depends(kubuntu), // reverse dependencies of kubuntu
?not(?reverse-depends(ubuntu-desktop)) // and not of ubuntu-desktop
), // that fulfills the condition above
?automatic // and is automatically installed
),
?not( // and also that are not
?or( // either required nor important
?priority(required),
?priority(important)
)
)
)
ubuntu-desktop因为?not(?reverse-depends(?exact-name(ubuntu-desktop))))。因此，您显然做错了。

尝试从软件中心安装Synaptic软件包管理器。
或者只是输入一个终端： sudo apt-get install synaptic
安装并打开程序后，在“部分”选项卡中，找到“ KDE桌面环境”部分，然后选择所有已安装的（绿色）选择（Ctrl + Click）。然后右键单击，选择完全删除并通过单击窗口顶部的绿色复选标记来应用更改。
您可以使用apt-rdepends查找已由（元软件包）安装的所有软件包，kubuntu-desktop 并将列表用作的输入apt-get purge。可能清除kdelibs *就足够了。
另一种可能性是删除Qt（即libqt4 *），因为KDE依赖于qt，它将删除所有KDE软件包。但是，如果在其他桌面上使用其他Qt应用程序，这将无法很好地工作。
但是，无论如何，apt-get都要非常仔细地检查要删除的软件包，因为这样可能会使整个安装混乱。
这为我工作：
sudo apt-get install tasksel
sudo tasksel
在列表中找到Kubuntu桌面并删除其选择。阅读并确认道具。
在这之后我也做了
sudo apt-get autoremove
答案是：https : //help.ubuntu.com/community/PureGnome 和 http://www.psychocats.net/ubuntu/puregnome
1）选择与您的ubuntu版本相对应的方法
2）检查您从KDE环境方案想保持，因为你需要它和）从删除列表中删除它（与依赖关系）或b）留在名单和以后重新安装。
3）复制/粘贴命令该命令如本网页所述，取决于您的版本，但通常看起来像：
sudo apt-get remove akonadi-backend-mysql akonadi-server akregator amarok amarok-common amarok-utils apport-kde apturl-kde ark bluedevil cdparanoia cdrdao
.... and a lot of packages
该命令无论如何都不会删除配置文件，只会删除程序。如果还希望删除配置文件，则将--purge选项添加到命令中。
4）
这些删除命令是根据将Kubuntu，Xubuntu等软件包添加到默认Ubuntu安装中创建的。这些命令可能会删除自从添加到默认目录之后要保留的某些其他软件包。如果是这种情况，请跟踪那些软件包并重新安装它们。您的设置应该仍然存在。
与往常一样，在修改分区之前先对其进行备份。
干杯，拉夫
我已经在ubuntu 14.04.5 LTS中使用了此命令，执行完之后，我的系统就像在以前的状态下一样工作，您可以使用commmand
