yum install 在嘗試從 rhel-x86_64-server-6 安裝時拋出錯誤 403

首先，我沒有太多的紅帽經驗。我的大部分經驗是使用 Ubuntu。我現在正在使用的伺服器正在執行 Red Hat Enterprise 6.5。

我正在嘗試做一個簡單yum install ncurses-devel的 403 錯誤，但我遇到了一些問題。如果我嘗試安裝 gdal，我也會得到同樣的結果。問題似乎特別是 rhel-x86_64-server-6，但我不知道為什麼。

$ sudo -E yum install ncurses ncurses-devel

我該如何解決？有關係subscription-manager嗎？

我能夠通過改變來解決這個問題

sudo -E yum install ncurses ncurses-devel

到

sudo yum install ncurses ncurses-devel

我之前遇到了一些sudo yum無法訪問外部世界的問題（因為我的工作代理），但顯然這就是這個問題的原因。
