My home desktop machine runs Centos 7.9
Due to the Centos issues I want to migrate to Almalinux (8 or later).
I updated Centos 7.9
I found a/the site with the Elevate/Leapp route, so I started there.
After making steps as in the description (on that page), in
Leapp I did the preupgrade check, and that returns some issues which
seem to block the process:
>>> start of last part of screen output:
==> Processing phase `TargetTransactionCheck`
====> * local_repos_inhibit
Inhibits the upgrade if local repositories were found.
====> * dnf_transaction_check
This actor tries to solve the RPM transaction to verify the all package dependencies can be successfully resolved.
Applying transaction workaround - yum config fix

I guess, something in python-2.7 is a problem;
I guess, something in leapp-repositories is a problem.
and maybe the AttributeError...
Being a simple and old Centosuser, I do not know how to solve this.
Can any member give the help to overcome this blocking?
Note: my Centos 7.9 uses 'yum' and not 'dnf' as a manager.
