我安装了带有 Unity 的 Ubuntu，还安装了 Kubuntu。我更喜欢 kubuntu，想删除 Unity 和所有 gnome 程序。我想知道，既然这是我原来的桌面环境，删除它是否会影响我，甚至可能吗？如果会，我不知道具体会怎样，所以能告诉我就太好了。谢谢

注意：仅删除ubuntu-desktop不会卸载所有 Gnome 软件包。
答案2
尝试：
sudo apt-get remove ubuntu-desktop # TO remove unity with all the applications that ubuntu comes with
或者
sudo apt-get remove unity-* # To remove only unity
希望这对你有帮助
