bcmwl error from DKMS Edit (4.8 KiB, text/plain)

I installed linux-kernel-4.16.0-041600-generic, I'm able to boot it but Broadcomm WiFI driver which I supsected as a reason fails:

Attached.
Meanwhile there was standard kernel upgrade 4.13.0-39-generic and it does work(including WiFi and with secure boot enabled(after manually signing wl.ko module)) in opposite to 4.13.0-37-generic and AFAIR 4.13.0-38-generic.

So my problem was solved but I'm open do debug it further. One thing which changed also I did:
apt-get install libelf-dev because of some warning from DKMS suggesting that during 4.16 kernel post-install.

If this issue doesn't happen to Bionic (which uses v4.15 based kernel), I think it's reasonable to upgrade. The bcmwl should work be able to build against v4.15.
