为了说明这一点，我没有太多的红帽经验。 我的大部分经验都是在Ubuntu上。 我正在使用的服务器正在运行Red Hat Enterprise 6.5。
我试图做一个简单的yum install ncurses-devel ，但我有一些403错误的问题。 如果我尝试安装gdal，我也会得到相同的结果。 问题似乎与特别是rhel-x86_64-server-6，但我不明白为什么。

我该如何解决？ 它与subscription-manager有什么关系？
我能够通过改变来解决这个问题
sudo -E yum install ncurses ncurses-devel
至
sudo yum install ncurses ncurses-devel
我之前sudo yum无法访问外部世界（因为我的工作代理），但显然这是这个问题的原因。
