Install/recover wifi Broadcom drivers Ubuntu 16.04 xenial (Dell XPS 13)

The problem

I just upgraded from Ubuntu 15 to Xenial and my wifi drivers in the new kernel version (4.4.0-21-generic) stopped to work.

The solution

I downloaded on a pen drive the following packages:

And installed them manually on the new kernel:
# First uninstalled the old stuff
sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get remove --purge dkms

# Installed the new packages
sudo dpkg -i dkms_2.2.0.3-2ubuntu11_all.deb
sudo dpkg -i bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu8_amd64.deb

During the installation of the drivers I got a weird error:
modprobe: ERROR: could not insert 'wl': Required key not available

Googling a little bit I found out that the problem is caused by the Secure Boot option in the BIOS:

Disabling that specific option the module started to work.
