Description

After installing rudder-agent on CentOS 8, it was globally working, but soon to notice that every directive making use of built-in techniques related to package management would fail and bail in error, including :

- “Packages” built-in technique
- “Sudoers” built-in technique

Checking rudder agent run it appears to complain about missing python2 :
/var/rudder/cfengine-community/modules/packages/yum: line 10: exec: python2: not found

Then :
info: Error occurred while getting supported API version.
error: Unsupported package module wrapper API version: -1
error: Some error occurred while contacting package module for promise 'sudo'

Installing python2 `yum install python2` solves this.

So either our package misses a dependancy to python2, or we install a cfgengine “yum” module that wants python2 when the others are happy with python3 and this wasn't detected.

Rudder_agent_recommends_230707a.png

After more research and advice it appears that no ptyhon interpreter was installed at all.

Uninstalling python2 and installing python3 works as well.

I believe a working python interpreter should be a dependancy of rudder-agent.

It doesn't seem to be even in the “recommends” section.

This might be a duplicate of #19904
