I think it has something to do with updating the Linux security policy. But how do you solve it...
Hi @MAKCOFF.
Apparently this is a UEFI enabled secure boot issue. Take a look at the link: https://askubuntu.com/questions/1114867/operation-not-permitted-when-trying-to-modprobe-xpad

Many thanks! Indeed, that was the problem.
