我尝试ia32-libs在 Precise 上安装（它是 CrossOverPro 的依赖项，这实际上是我想要实现的，但我认为这不相关）。该软件包无法安装，跟踪报告的未满足依赖项链，我找到了libgnome-keyring0，由于两个未满足的依赖项（似乎都已安装）而无法安装。这让我不知道该如何继续。
以下是我所经历的步骤的日志：

顺便说一句，我不知道为什么libpurple0会出现在倒数第二步。
因此，我的包结构显然有问题，但我不确定如何调试它或解决根本原因。
答案1
打开 synaptic 并在搜索中输入其名称（不是完整名称，只是部分名称，如keyring或libgnome-keyring或libfar等）。你可能发现这些包-dev也有一些文件。尝试安装它们。在大多数情况下，这可以解决问题
