我使用 Siduction，它是一个滚动发布的 Debian 发行版，运行于 sid 分支。
尝试更新我的系统，但我似乎无法安装 libghc-xmonad-dev 和 libghc-xmonad-contrib-dev。我需要这个来使用 xmonad。有什么建议么？
> apt-get install libghc-xmonad-dev libghc-xmonad-contrib-dev

这是使用基于 Sid 的滚动发布的陷阱之一。 Haskell 包正在经历一个重建，因此 Sid 中的包树相当损坏。
您必须等待 Sid 中的情况得到解决，或者使用巴斯特版本其所有依赖项都可用。后者是Siduction手册中有解释。
