我最近切换到 Linux，在切换之前对它的工作原理有很好的了解，因为我有几个月使用基于 Ubuntu 的服务器的经验。我一直在尝试安装一个基于开源库的 LEGO CAD 程序。有关该程序的信息这里。我正在查看的程序名为 Konstruktor，它大部分情况下应该可以正常工作。但是似乎有一个依赖项无法安装。缺少的依赖项是“kdelibs5”，我知道它是什么以及它的用途，但无法安装它。尝试安装时，我收到此错误：
george@GEORGE-PC:~$ sudo apt-get install kdelibs5
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package kdelibs5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'kdelibs5' has no installation candidate
当我尝试为我的系统安装正确的 Konstruktor 包时，出现此错误：
george@GEORGE-PC:~$ sudo dpkg -i '/home/george/Downloads/konstruktor_0.9-beta1-2_amd64.deb'

我尝试过更新和添加 KDE 软件包的 apt 存储库，但一直出现相同的错误。我尝试了软件包“kdelibs5-dev”，安装成功，但“kdelibs5”安装失败，Konstruktor 仍然无法安装。我在 Ubuntu 13.10 上使用 GNOME shell，架构为 amd64。如能得到任何帮助，我将不胜感激。
提前致谢。

您是否尝试过安装kdelibs5deb 文件比如这个直接地？
