Install SnapAPI kernel module

Hi guys !

I´m testing a new backup product in my SLES Lab and need to update the kernel with SnapAPI, I´ve tried install kernel modules to that, but always that it will download the right version, it fails (5.3.18-59.27-default).

System: SLES 15 SP3
Kernel: 5.3.18-59.27
Host: Hyper-V over Win10

How can I download the kernel-source ? I tried using zypper and YAST and got the same error all the time.
