TiniHub Inc.

When Upgrading the Alma or RedHat Linux, Leapp tool give error or warning like "Inhibitor: LUKS encrypted Partition Detected." 

If Upgrading on CEPH node where using LUKS encryption then you may face
     # Error: Inhibitor: LUKS encrypted partition detected
# Take backup of your actor file and create new with below code and then edit answerfile too and re-run leapp preupgrade will resolve your issue. 

mv /usr/share/leapp-repository/repositories/system_upgrade/common/actors/inhibitwhenluks/actor.py /usr/share/leapp-repository/repositories/system_upgrade/common/actors/inhibitwhenluks/actor.py.org

Then re-run leap preupgrade, it will resolve your error.
