最近在更新CentOS 软件包时电脑意外重启后，进不了最新的内核，用以前的内核进去执行yum update 出现一下问题：
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，有未完成的yum事务，建议先运行yum-complete-transaction命令清除。
在网上找到一下解决方法：
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
