• Ranjith tried to test for rhel10 x86, but it failed. He is working on a proper fix/procedure for rhel10 which might take some time. He will confirm post that and the update will be done. Since this ticket was for RHEL 9, closing this ticket as the task is complete. Opening a new ticket for RHEL 10 and the update will be tracked within that ticket.
