Confirmed
Bug description:
After updating ubuntu 16.04 to latest kernel 4.4.0-21, bcmwl driver
(package bcmwl-kernel-source) does not load and wifi not work.
sudo modprobe wl
modprobe: ERROR: could not insert 'wl': Required key not available
If I boot with kernel 4.4.0-18 - bcmwl loads normally and wifi works.
