I just followed the instructions to install Broadcom Drivers,every thing is working but at last instruction sudo apt-get install <bcmwl-kernel-source>,it just say:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package bcmwl-kernel-source

And no thing happened after I rebooted my system. I use Ibuntu 15.04 and pci id is [14e4:4365] (rev 01)
