Comment 24 for bug 1572659

As well here is an example if the MOK util that will popup when you reboot https://sourceware.org/systemtap/wiki/SecureBoot

FWIW my PCI.ID isn't on the list mentioned here https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers/60395#60395, it's possible I am stupidly trying to use the wrong package.
