问题描述
我安装了kubuntu-desktop只是为了试验其界面。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？
最佳思路
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kubuntu-desktop依赖但不依赖ubuntu-desktop的任何程序包。而且，这种方法有点贪心。它将删除Qt软件包，ergo mplayer2，VLC，并且所有依赖于Qt库的软件包都可能被删除。在末尾添加那些带有加号(+)的软件包，例如ubuntu-desktop软件包。对于其他口味：
Xubuntu
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(xubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' xubuntu-desktop+
Lubuntu
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(lubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' lubuntu-desktop+
Gnome
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。如果您使用了kde-core或其他元软件包，则应使用元软件包的名称替换”kubuntu”。
了解智能搜索
为了确切说明选择了哪个软件包，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)
)
)
)

第三种思路
尝试从软件中心安装Synaptic软件包管理器。
或者只输入一个终端：sudo apt-get install synaptic
安装并打开该程序后，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。
第四种思路
由于Braiams对我不起作用，所以我做了以下事情：
转到/var /log /apt并在history.log(或任何压缩的history.log。[n] .gz文件)中搜索”kubuntu-desktop”，以查找与kubuntu-desktop一起安装的确切软件包并删除它们。
第五种思路
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
第六种思路
您可以使用apt-rdepends查找(元软件包)kubuntu-desktop已安装的所有软件包，并将该列表用作apt-get purge的输入。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会删除所有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，都应非常仔细地检查apt-get要删除的软件包，因为这样可能会使整个安装混乱。
