整个 texlive 发行版都是通过 来安装的apt-get。唯一的例外是pgfmanual.pdf适当的，我将其解压，因为texdoc阅读存档手册时遇到了麻烦。也就是说，在我更新到 saucy 之前，texdoc pgf它运行良好。
我如何将 texdoc 指向正确的方向？
答案1
这是 Debian/Ubuntu 软件包中的一个错误。Debian TeX 政策明确规定，文档（或指向它的符号链接）应放在 texdoc 搜索的位置，但这里没有这样做。您应该在 Debian 和/或 Ubuntu 错误跟踪系统中报告该错误。
在等待错误修复时，在 texdoc 搜索的地方建立符号链接确实是一个很好的解决方法。
答案2
根据@jon 的意见，有一个简单的解决方法可以解决此问题。
ln -s /usr/share/doc/texmf/pgf/pgfmanual.pdf ~/texmf/doc/pgf/pgfmanual.pdf
texdoc pgf现在可以按预期工作。
