Your kernel header files aren't properly installed.

My installation stops here, what do I do wrong?

• Errormessage when run the installation script (install-driver.sh) $ sudo ./install-driver.sh

$ sudo ./install-driver.sh
Your kernel header files aren't properly installed.
Please consult your distro documentation or user support forums.
Once the header files are properly installed, please run "sudo ./install-driver.sh"

Dont know exactly how to fix the kernel headers...

$ sudo apt install kernel-headers
