Centos2alma-1.4.0 - ERROR global name 'dnf' is not defined

[superchecco99]

Hi, I am running Centos2alma-1.4.0 on Product version: Plesk Obsidian 18.0.62.2 OS version: CentOS 7.9.2009 x86_64
When performing Centos2alma it stops with errors:

File "/usr/share/leapp-repository/repositories/system_upgrade/common/libraries/repofileutils.py", line 54, in get_repodirs
with dnf.base.Base() as base:

The dnf python2 module should be installed along with the leapp packages because it is required for leapp. Can you check if the python2-dnf package is installed?
If the package is installed, do you have any custom settings in the path variables ($PATH, $PYTHONPATH, etc)?
