Error: Bad return status for module build on kernel: 4.9.0-2-amd64 (x86_64)

[faber]

I'm trying to adopt the kernel image 4.9.0-2-amd64 on my Debian 9
TemplateVM.

After installing the image and its headers, I do the following command:

--------------------------------------
sudo dkms autoinstall -k 4.9.0-2-amd64
--------------------------------------

And get the following output:


-------------------------------------------------------------------------
Kernel preparation unnecessary for this kernel. Skipping...

Building module:

make -j2 KERNELRELEASE=4.9.0-2-amd64 KVERSION=4.9.0-2-amd64...(bad exit

And the output of /var/lib/dkms/u2mfn/3.2.3/build/make.log is:

Any idea?

Thanks in advance

This has happened because 'qubes-kernel-vm-support' package using the outdated 'u2mfn.c'.

Refer to this issue: https://github.com/QubesOS/qubes-issues/issues/2691

At the moment, you can simply fix this by copy the updated 'u2mfn.c' and replace your old one here: https://github.com/QubesOS/qubes-linux-utils/blob/master/kernel-modules/u2mfn/u2mfn.c

or just edit your 'u2mfn.c' and add the related lines from here: https://github.com/QubesOS/qubes-linux-utils/commit/e01745f66fd2b4b0035ce7e064f340faeb997675

Hope this help :)
