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
