解决执行"yum-complete-transaction"命令时提示"except yum.Errors.RepoError, e:"错误问题

问题

更新Jenkins时系统卡住，就Ctrl+C强制取消了本次安装，但是yum的本次事务仍然存在，重新执行安装命令会显示以下内容

正在解决依赖关系
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

按照提示执行yum-complete-transaction --cleanup-only会报以下错误

[root@localhost ~]# yum-complete-transaction --cleanup-only
  File "/usr/sbin/yum-complete-transaction", line 146
    except yum.Errors.RepoError, e:
                               ^
SyntaxError: invalid syntax

原因

yum-complete-transaction命令本质是一个python脚本，依赖python2，由于系统中存在python2和python3，默认执行python命令会执行python3

[root@localhost ~]# python -V
Python 3.9.9

解决

修改yum-complete-transaction中的python依赖指向

[root@localhost ~]# vim /usr/sbin/yum-complete-transaction

#!/usr/bin/python2 -tt

................

import logging
import os
import os.path

将#!/usr/bin/python -tt修改为#!/usr/bin/python2 -tt

保存后再次执行命令即可

[root@localhost ~]# yum-complete-transaction --cleanup-only
