系统版本为：
[root@s10 ~]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)
由于管理kvm虚拟机的需求，需要安装GNOME Desktop 和Graphical Administration Tools 桌面服务。
通过
[root@s10 ~]# yum groupinstall "GNOME Desktop" "Graphical Administration Tools" -y
时出现如下错误提示：

错误概要
-------------
该问题是由于文件fwupdate-efi 同grub2-common冲突所致，这里需要将该包通过yum update grub2-common命令进行更新。
