今天早上我在服务器上安装了 Ubuntu Server 14.04，我认为运行 GUI 会很酷。尽管它占用了太多内存，我不喜欢。我怎样才能永久恢复到 CLI？还有我怎样才能删除 KDE 让它永远不存在？
我已尝试过sudo apt-get remove kubuntu-desktop && sudo apt-get remove autoclean但它仍然存在。
答案1
通过重新安装，这是删除 kubuntu 桌面包最安全的方法：
sudo apt-get install aptitude ubuntu-minimal
sudo aptitude remove '?and(?reverse-depends(kubuntu)),?not(?reverse-depends(?exact-name(ubuntu-minimal))))'
这将使您的系统保留 Ubuntu 的最小安装，足以启动，而不需要 Kubuntu 软件包。
解释 aptitude 的作用：
?and(conditional1, conditional2)：搜索所有满足两个条件的包。?reverse-depends(package)：搜索所有包含该包的反向依赖的包package。?not(package)：搜索不满足此条件的包。?exact-name(package)：使用?name()它时搜索任何包含名称的包，例如它会找到package、libpackage0和package-gui。用?exact-name它指定应该是确切的名称，相当于^package$正则表达式。
如果我们用简单的英语来解释它：aptitude，remove任何具有反向依赖kubuntu有一个包，它的名字中包含不是反向依赖具有精确名称的包ubuntu-minimal。
答案2
如果您今天早上才安装，请重新安装。这是获得完美清白的最简单方法（也是很好的练习）。
答案3
在终端：
sudo apt-get --purge remove kubuntu-desktop
- 清除标记您正在删除该包的所有配置
sudo apt-get autoremove
删除所有依赖于 kubuntu-desktop 的孤立软件包
