使用 yum install nfs-utils -y 时 

出现如下错误:



错误：gssproxy conflicts with selinux-policy-3.13.1-102.el7.noarch
 您可以尝试添加 --skip-broken 选项来解决该问题
** 发现 6 个已存在的 RPM 数据库问题， 'yum check' 输出如下：

解决方法：

首先：

yum install yum-utils -y

然后执行命令：

package-cleanup --cleandupes -y

如果还存在如下错误：

Not removing selinux-policy-3.13.1-102.el7.noarch because it is required by 2 installed packages
Not removing libselinux-2.5-6.el7.x86_64 because it is required by 1 installed package
There are unfinished transactions remaining. You might consider running yum-complete-transaction,
or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. 
If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).



再执行命令：

package-cleanup --cleandupes with --removenewestdupes -y



之后重新下载即可

yum install nfs-utils -y
