我已添加该链接中所述的安全密钥以及以下行 deb http://cran.r-project.org/bin/linux/ubuntu precise/ 到 /etc/apt/sources.list
我还添加了以下 ppa：sudo add-apt-repository ppa:marutter/rrutter。
任何帮助都将不胜感激。
PS：我也对 /var/lib/apt/lists 中的列表感到怀疑，所以我删除并重新创建了它。仍然有同样的错误。
【问题讨论】：
-
你有所有它说是未满足的依赖项的包吗？您需要那些
-dev包才能编译R的-dev包中的fortran 和c 代码。 -
不，我没有那些包。我搜索了它们，但我无法安装那些软件包。它显示的错误是：
Package gfortran is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source -
我还通过突触包管理器搜索了我有哪些损坏的包，但其中也没有列出损坏的包。
-
尝试分别安装每一个。
sudo aptitude search首先。您可能必须相应地更新名称。gfortran例如应通过以下方式安装：sudo apt-get install gfortran-4.6。 -
感谢您的帮助，但我已经尝试过这样做，但仍然遇到同样的错误。我安装了 gfortran 4.8 等，但错误仍然相同。
