今天在用yum安装软件出错几次户，总是有提示信息：

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.

意思是说存在没有完成的yum事务，建议先运行yum-complete-transaction命令结束它们。

处理步骤：

# 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
