Re: [yocto] [Scarthgap] "ModuleNotFoundError: No module named 'imp'"

Hello,
I'm not able to find log.do_configure from libdnf-native, but....

From the generated error.py of libdnf file I can read

# This file was automatically generated by SWIG (http://www.swig.org).
# Version 3.0.8
#
# Do not make changes to this file unless you know what you are
doing--modify
# the SWIG interface file instead.

Indeed I got that the proper version is the 4.2.1, but seems generated from
3.0.8 version
