RHEL-09-232250 - All RHEL 9 local files and directories must have a valid group owner.

Information

Files without a valid group owner may be unintentionally inherited if a group is assigned the same Group Identifier (GID) as the GID of the files without a valid group owner.

Solution

Either remove all files and directories from RHEL 9 that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command:

$ sudo chgrp <group> <file>
