CenOS 7.x yum更新意外中断，提示yum-complete-transaction

最近在使用yum -y update更新CentOS 7.x的时候终端不小心意外退出了，再次使用yum命令更新或安装软件的提示提示：

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.

The program yum-complete-transaction is found in the yum-utils package

解决办法如下

#安装 yum-complete-transaction

yum install yum-utils

#运行 yum-complete-transaction

yum-complete-transaction –cleanup-only

#清除可能存在的重复包

package-cleanup --dupes

#清除可能存在的损坏包

package-cleanup --problems
