使用 yum install nfs-utils -y 時
出現如下錯誤:
錯誤：gssproxy conflicts with selinux-policy-3.13.1-102.el7.noarch
您可以嘗試添加 --skip-broken 選項來解決該問題
** 發現 6 個已存在的 RPM 數據庫問題， 'yum check' 輸出如下：
libselinux-2.5-14.1.el7.x86_64 是 libselinux-2.5-6.el7.x86_64 的副本
libselinux-utils-2.5-14.1.el7.x86_64 是 libselinux-utils-2.5-6.el7.x86_64 的副本

selinux-policy-3.13.1-229.el7_6.12.noarch 是 selinux-policy-3.13.1-102.el7.noarch 的副本
解決方法：
首先：
yum install yum-utils -y
然后執行命令：
package-cleanup --cleandupes -y
如果還存在如下錯誤：
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).
再執行命令：
package-cleanup --cleandupes with --removenewestdupes -y
之后重新下載即可
yum install nfs-utils -y
