在使用yum 时总是有提示信息:
The program package-cleanup is found in the yum-utils package.
或者提示:
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:
#安装 yum-complete-transaction（这是一个能发现未完成或被中断的yum事务的程序）

yum install yum-utils

#清除yum缓存

yum clean all

#列出重复的包lists duplicate packages

package-cleanup --dupes

#删除重复的包 removes duplicate packages

package-cleanup --cleandupes

#清除可能存在的损坏包

package-cleanup --problems
