How do I fix cPanel/WHM reported error number 255

I am getting an email notification with the following message. Is there something I can address in my WHM to address this issue?
Thank you for your help.

The cPanel & WHM update process failed for the following reason:
Maintenance ended; however, it did not exit cleanly (256). The following events were logged: “scripts/findoutdatedservices”. Review the update logs to determine why the update failed.

Cheers @emilyjourney,

I'd first try a reboot and see if that does the trick. Are there any other symptoms besides the error?

I found a user with a similar issue. See here:

The post indicated that it was related to the kernel - especially if it was a custom distribution. You could always test by switching the kernel via the configuration profile or via our CLI.

You may also find more information in the log files:


It may be worth reaching out to cPanel as well. It's possible they have more knowledge about this issue.
