When you issue the command sudo dnf remove kernel-core-version to remove the Red Hat Compatible Kernel (RHCK) from the system, error messages similar to the following example might be generated:

...
Erasing   : kernel-core-version              4/4
warning: file /lib/modules/version/modules.builtin.modinfo:
 No such file or directory
...

You can ignore the messages. At the end of the operation, all RHCK related files are removed successfully.
