Rudder

I had a minimal centos8, without any python installed, the yum module failed, but I expected rudder to return a better error message:

If you tried to install a virtual package, please use in place the concrete package you want to install.
Presence of package nginx in any version could not be repaired

When the module fails to even call its API:

E| compliant     Inventory                 inventory                                    Next inventory scheduled between 00:00 and 06:00
