YUM client side script not deploying automatically

[swampdogmash]

I have a feeling there is an obvious answer to this, but I recently upgraded my CheckMK server from 2.3.0p17 to 2.3.0p18 (at home not the much larger install at work). I then upgraded the YUM MKP from 2.4.4 to 2.5.1 and re-baked packages for the single agent that I deploy the yum plugin onto using an agent rule. It is a Cloud edition server and I noticed that the AGENT upgraded, but the YUM plugin that was previously deployed into /usr/lib/check_mk_agent/plugins/300 was removed. No other options were changed, just an update to the plugin and the version number.

Has something changed in 2.5.1 from 2.4.4 that would prevent the plugin being packaged correctly into the RPM for install - I did open the RPM and there was no YUM plugin file in the archive.

@swampdogmash sorry for the late reply.
I installed plugin version 2.5.1 on a little outdated 2.3.0p9 Checkmk instance and found the plugin baked into the agent RPM file. Maybe latest Checkmk server version causes this problem?

The bakery plugin file in the MKP version 2.5.2 is empty.

[HenriWahl]

@gurubert which on exactly?

[gurubert]

This file was present but empty: https://github.com/HenriWahl/checkmk-agent-plugin-yum/blob/master/lib/python3/cmk/base/cee/plugins/bakery/yum.py

After I pasted the content the bakery was able to bake the plugin into the package.

How can this happen? I downloaded the MKP file and extracted all included TARs:

Edit: I think I found it...

[gurubert]

I don't know.

[HenriWahl]

I assume the file lib/python3/cmk/base/cee/plugins/bakery/yum.py should be moved completely to lib/check_mk/base/cee/plugins/bakery/yum.py?

[HenriWahl]

At least this was the location in the previously working 2.4.4 release. Comparing with https://github.com/HenriWahl/checkmk-agent-plugin-kubernetes-namespaces/blob/main/mkp/lib/python3/cmk/base/cee/plugins/bakery/kubernetes_namespaces.py this lib/python3-path should work anyway, so I am pretty confused.

[gurubert]

I assume the file lib/python3/cmk/base/cee/plugins/bakery/yum.py should be moved completely to lib/check_mk/base/cee/plugins/bakery/yum.py?

Both are the same path. $OMD_ROOT/local/lib/check_mk is a symbolic link to $OMD_ROOT/local/lib/python3/cmk.

[HenriWahl]

So this gets even weirder, especially while the MKP I downloaded contains all needed files.
