How can I use this script for 5.13.0-21-generic? Is there a workaround?

@mousemat86: I had 100% success rate (mind you 3 out of 3) when I've removed the doc part of the patch. But then I comment out half of the script and change the logic of other half (don't clean, don't download the patch if it's there, skip questions, etc.).
