Installation of proprietary NVIDIA driver fails for kernel 4.9: version.h is missing

Hi,
upgraded my tumbleweed system today and got the new kernel 4.9, as usual i had to install the proprietary NVIDIA driver afterwards.
But this time the installation failed with the following error message:

ERROR: Neither the '/usr/src/linux/include/linux/version.h' nor the '/usr/src/linux/include/generated/uapi/linux/version.h' kernel header file exists. The most likely reason for this is that the kernel source files in '/usr/src/linux' have not been configured.

This is not the first time i upgrade the kernel and install the nvidia driver on this system, which means i have all the necessary devel packages installed.
I also try to install the newest nvidia version 375.26, which also was installed before the kernel upgrade.

Ok this is the output:

My understanding is that there was a problem with the devel package should be corrected now

As you can see, no kernel-devel for 4.9.0-2.1

Yep and it should now be availbale. Do an update

Thank you, it is working now.
