Update 21.1.5 Failing

When attempting to update to 21.1.5 I keep receiving the following error message:

***GOT REQUEST TO UPDATE***

Is there a way to fix this error?

I would try switching the mirror you are using, it is possible the copy on the mirror you are currently using is corrupted, switching mirrors will give you access to a different copy of the file.

Go to System > Firmware > settings tab > mirror
