故障排除

我在 VirtualBox VM 上安装了 Debian 8.2，并添加了不稳定（sid）存储库，而/etc/apt/sources.list无需删除任何其他存储库，然后我运行了apt-get update && apt-get upgrade && apt-get autoremove.在此之前，我安装了 Plasma 4，我希望添加此存储库会给我 Plasma 5，但我根本没有安装 Plasma 桌面，或者看起来是这样。每当我跑步时：

apt-get install kde-full

我收到错误：

The following packages have unmet dependencies:
 kde-full : Depends: kde-plasma-desktop (>= 5:84) but it is not going to be installed
            Depends: kde-plasma-netbook (>= 5:84) but it is not going to be installed
            Depends: kdeartwork (>= 4:4.11.3) but it is not going to be installed
            Depends: kdenetwork (>= 4:4.11.3) but it is not going to be installed
            Depends: kdeutils (>= 4:4.11.3) but it is not going to be installed
            Depends: kdepim (>= 4:4.11.3) but it is not going to be installed
            Depends: kdeplasma-addons (>= 4:4.11.3) but it is not going to be installed
            Recommends: kde-standard (>= 5:84) but it is not going to be installed
            Recommends: kdewebdev (>= 4:4.11.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

每当我尝试使用apt-get install类似的方式安装特定的 Plasma 组件apt-get install kde-plasma-desktop时，我都会遇到类似的错误，最后一行完全相同（即E: Unable to correct problems, you have held broken packages.）。

故障排除

就故障排除而言，我用谷歌搜索E: Unable to correct problems, you have held broken packages.并找到了问题“修复 debian 上损坏的软件包？“ 和 ”E：无法纠正问题，您持有破损的包裹”并尝试过：

apt-get install -f kde-full

它返回与没有该选项的运行相同的错误-f。我也跑了apt-get -f install，它刚刚返回：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我也尝试过运行：

aptitude why-not kde-full

和

aptitude why-not kde-plasma-desktop

并且都返回：

Unable to find a reason to remove ...

其中 ... 是后面提供的包名称aptitude why-not。虽然apt-mark showhold没有返回任何输出。
