我尝试在 RHEL 5.5 系统上远程安装 R，但始终遇到依赖性问题
yum -y install R
结果如下
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
我已经尝试了yum clean all可能的解决方案，但它导致了同样的问题。我也尝试过单独安装依赖项，但它们似乎不存在。
我该如何解决这个问题，为什么包管理器会认为依赖项缺失，而实际上并不存在？
答案1
CentOS 5.5 已经很老了。它于 2010 年发布。EPEL 的目标是主要版本的最新版本，这意味着它的目标是 5.11。您已经远远落后并期待 EPEL 为您提供支持。
我的猜测是你需要更新。您可能依赖的某些软件包仅随较新版本的 5.x 一起提供。
提醒您，5.x 已于 2014 年停止修复，并将在不到一年的时间内完全停产。您应该有某种更新计划。
