RedHat：无法安装GNOME桌面环境包

我在运行Red Hat 6.4版的机器上安装了GNOME桌面环境包。

more /etc/redhat-release Red Hat Enterprise Linux Server release 6.4 (Santiago) 

在安装结束时，我收到了有关缺lessRPM-GPG-KEY-oracle目录的错误。

  [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM- GPG-KEY-oracle 

我该如何解决这个问题？

 [root@MY_BABY ~]# yum groupinstall "X Window System" "GNOME Desktop Environment" Loaded plugins: product-id, security, subscription-manager This system is receiving updates from Red Hat Subscription Management. ol6_UEK_latest | 1.2 kB 00:00 ol6_latest | 1.4 kB 00:00 rhel-6-server-rpms | 3.7 kB 00:00 rhel-6-server-rpms/primary_db | 30 MB 00:07 . . . . . . --------------------------------------------------------------------------------------- --------------------------------------------- 1.8 MB/s | 34 MB 00:18 warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM- GPG-KEY-oracle 

我也试过这个

• 为什么GNOMEterminal使用这么多的内存？
• Ubuntu服务器10.04不会自动启动到已安装的Gnome桌面
• GNOMElogin后的Linux启动脚本
• 扩展名为基础的文件关联
• 在terminal中右击打开新窗口…停止这个？

但仍然没有/etc/pki/rpm-gpg/下的目录。

 ls /etc/pki/rpm-gpg/RPM- GPG-KEY-oracle 

这是我在/etc/yum.repos.d ：
