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/python -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
