For now, I’ve removed the conflicts by disabling the appstream, centos-ceph-pacific, and centos-opstools repos. Any additional tips on which repos should be enabled and/or how to address the package conflicts would be greatly appreciated. Thanks again, Devin On Aug 11, 2026, at 1:53 PM, Devin A.

Hello,

What yum repositories should be enabled on a 4.5.7 self-hosted engine VM running AlmaLinux 9.8? We successfully updated our cluster (hosted engine VM And all hosts), but are getting the following conflicts when trying to update the VM itself.

Many thanks, Devin
