ID: PACKAGES_ACROSS_MAJOR_RELEASE
Name: Installation of packages across major releases is not supported

The recommendation hints the packages might be a leftover from the leapp upgrade process. See attached screenshot.

However, leapp packages must be first removed from the exclude list in dnf.conf before they can be removed. The suggested resolution will fail otherwise:

# grep exclude etc/dnf/dnf.conf
--- 
exclude=leapp-upgrade-el8toel9,python3-leapp,snactor,leapp
—

This prerequisite is mentioned in the leapp docs (RHEL 9 [0]; RHEL 8 [1]) but it would be nice to have it in the recommendation as well.
