两年前，当最后一个 LTS 发布时，我决定在我的个人安装上安装 KDE（桌面版或完整版，不确定哪个）Ubuntu 升级后从 10.04 升级到 12.04。现在 14.04 版本已经发布，我打算再次升级我的系统。
问题是，由于我安装的是 Ubuntu，而不是 Kubuntu，我不确定哪种升级路径最安全。我知道会有变化，但基本上我不想失去全部我过去两年的模组。（例如：自定义下载：启动屏幕、桌面效果、鼠标指针）解决方案还必须包括事后安装程序的设置。（例如：yakuake）
我认为，有两种可能的方法可以做到这一点。类似于讨论的内容这里：
- 全新安装 Kubuntu 并移动设置。
- 更新 Ubuntu 和 KDE。
我怀疑 #2 是更安全的途径。但话又说回来，如果有办法正确地迁移所有设置，#1 将提供更精简的安装。我真的必须向专家致敬。
需要注意两点：
- 我已经拥有我的分区的 dd 备份，因此我可以进行实验。...在合理范围内...我宁愿在一周内完成设置。
- 我有绝对零执着GNOME 中的任何内容。

然后运行此命令来安装 KDE 桌面。
sudo apt-get install kubuntu-desktop
然后运行 Ubuntu 基础更新：
sudo do-release-upgrade -d
您现在正在运行 Kubuntu 14.04LTS。
答案2
问题是，由于我安装的是 Ubuntu，而不是 Kubuntu
实际上，软件包基础是相同的。自启动以来安装的软件包与之后安装的软件包之间没有区别。那么，唯一的缺点是什么？您可能需要安装/升级大量软件包才能进行跳转。无论如何，这都不是强制性的。您只需升级即可。
在我看来，有两种可能的方法可以做到这一点
实际上是三个。正如我提到的，你只需要升级，而不需要删除任何东西。升级系统旨在在版本之间无缝升级。
