Cause

yum update command installs the python2-leapp-0.16.0-2.el7.noarch package, while the leapp-0.14.0-1.el7.noarch specifically requires python2-leapp = 0.14.0-1.el7. The downloaded version is causing the conversion to fail due to inconsistency.

This is a bug with ID #PAUX-6405, which is fixed in the latest script iteration 1.4.0.

Resolution

Download the latest script version from the article How to make an in-place upgrade of a Plesk server from CentOS 7 to AlmaLinux 8? and re-run the conversion.
