我想在远程 CentOS 7.2 中安装X Window System（我使用 ssh 登录服务器），但出现以下错误：
[root@localhost ~]# yum groupinstall "X Window System"
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: centos.01link.hk
* extras: centos.01link.hk
* updates: centos.01link.hk
Maybe run: yum groups mark install (see man yum)
No packages in any requested group available to install or update
为什么我无法安装X Window System？

我读这个帖子。
看来很多人都有这个问题，而且没有解决办法。

我使用以下命令列出隐藏的组。
# yum group list hidden
