添加 KDE Backports PPA 导致依赖关系未得到满足。如何解决？

我ppa:kubuntu-ppa/backports按常规方式添加，然后执行dist-upgrade。它需要下载超过 GB 的文件，所以我把它留到下午。回来后，我发现系统变得非常不稳定且无法使用。

我登录控制台并从那里重新启动它，当我回来时，事情有点混乱。

我运行sudo apt-get -f dist-upgrade后发现输出内容如下：

The following packages will be upgraded:
  kdm
1 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
2 not fully installed or removed.
Need to get 0 B/2,227 kB of archives.

理想情况下，我希望满足依赖关系，因此如果可能的话，有人可以建议如何做到这一点吗？如果做不到，请建议如何恢复到以前的配置。

谢谢。

使用内核为 3.8.0-34-generic 的 Ubuntu 12.04 #49~precise1-Ubuntu

答案1

所有软件包必须是同一版本：

sudo apt-get update
sudo apt-get install kdm=4:4.11.3-0ubuntu0.1~ubuntu12.04~ppa1 kde-workspace-data=4:4.11.3-0ubuntu0.1~ubuntu12.04~ppa1 kde-workspace-kgreet-plugins=4:4.11.3-0ubuntu0.1~ubuntu12.04~ppa1

此后您应该再次检查：sudo apt-get check。应该没有任何其他错误。

如果由于某种原因上述解决方案不起作用，请使用aptitude：

sudo apt-get install aptitude
sudo aptitude -f install

它应该会向您展示一系列可能的解决方案，选择不卸载任何软件包和/或升级软件包的解决方案。我目前无法提供示例。

怀疑：我相信kde-workspace-data更新得太晚了，可能会破坏一些东西（kdm），但由于某种原因，kdm 不是同一版本（该死的 PPA 维护者），因此安装4:4.8.5-0ubuntu0.3和升级 kdm 应该可以解决问题：

sudo apt-get install kdm=4:4.11.3-0ubuntu0.1~ubuntu12.04~ppa1 kde-workspace-data=4:4.8.5-0ubuntu0.3 kde-workspace-kgreet-plugins=4:4.11.3-0ubuntu0.1~ubuntu12.04~ppa1

答案2

软件包可能处于非常糟糕的不一致状态，您应该通过以下方式重新安装它 -

sudo apt-get --reinstall install kubuntu-desktop

并重新启动一次，希望它能工作。如果不行，请通过以下方式禁用 kubuntu backports 存储库，Software & Updates > Other Sources然后尝试

sudo apt-get update
sudo apt-get install kubuntu-desktop

这次它可以起作用了。
