  bcmwl driver does not work with kernel 4.4.0-21 when secure boot

Status in bcmwl package in Ubuntu:

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.

  If secure boot disabled - bcmwl loads normally with kernel 4.4.0-21
  and wifi works.
