当我尝试安装 Nemo 时，为什么 apt-get 想要安装 Cinnamon？

我的 Unity 壁纸开始出现异常几周前，经过一番搜索，我终于明白是 Cinnamon 搞错了。我从来没有自己安装过 Cinnamon，但使用过 - 我是说用过 - Nemo。在包目录中没有提到 Cinnamon 软件包是依赖项，但它们肯定已安装。不过有件事我无法解释：我在 10 月份升级到 Ubuntu 13.10 后立即安装了 Nemo，大约 2 个月内 Unity 与 Nemo 无缝共存；我怀疑 Cinnamon 只是在升级期间安装的。

现在的问题是为什么 Nemo 依赖列表与apt-get包目录中的不同：

如果能使用 Nemo 而没有那么多麻烦那就太好了。谢谢。

更新：输出apt-cache policy：

您正在从 ppa 安装 nemo。这些软件包不遵循与存储库中的软件包相同的依赖关系。

这是 PPA：

dpkg-deb --info nemo_2.0.8-20140108010047-saucy_amd64.deb 
 new debian package, version 2.0.

 Package: nemo

这是存储库：

apt-cache show nemo

如您所见，PPA 末尾包含 cinnamon 包，而 repo 中没有。如果您预计 cinnamon 不会安装，则应删除 PPA 并使用存储库，或者打开 bug 以删除 cinnamon 依赖项。
