Check_yum.py not working on CentOS9

[e36Alex]

Hello,

i tried to use check_yum.py at a CentOS9 (Python 3.9.14) installation and get the following error:
`[root@ds ~]# sudo /usr/lib/nagios/plugins/ext/check_yum.py -vvv
Nagios Plugin for Yum updates on RedHat/CentOS systems - Version 0.12.7

setting plugin timeout to 30 seconds
running command: /usr/bin/yum --security check-update

YUM WARNING: Cannot find summary line in yum output. Please make sure you have upgraded to the latest version from https://github.com/HariSekhon/Nagios-Plugins. If the problem persists, please raise a ticket at https://github.com/HariSekhon/Nagios-Plugins/issues with the full -vvv output`

Thanks for your help!

When there updates available, the output is "ok".

YUM OK: 0 Security Updates Available. 73 Non-Security Updates Available

Was expecting, that non-security updates will be a warning an security update will be an error and no updates is "ok"

If you want to warn on any update, then use the --all-updates switch.

The code probably needs some updating for the issue above, will look at it later.

One more addition:
When i set --all-updates, i get:
YUM OK: 0 Updates Available
