Ubuntu
b43-fwcutter package

b43 module/driver not being copied to /lib/modules/[kernel]

Asked by TGP1994

Despite installing both b43-fwcutter and firmware-b43-installer (and letting it run the download/extraction process), no b43 module exists in /lib/modules/[current kernel version] as modprobe b43 results in:

modprobe: FATAL: Module b43 not found in directory /lib/modules/4.4.0-79-generic

At what point is the module installed to that directory?

Yes, to the letter. https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Switching_between_drivers is the step I'm getting hung up on, as it seems the kernel module just doesn't exist. I realize now though that this package probably isn't responsible for putting the module file in there... But why it's missing is beyond me.

Yikes, I think I may have figured out my problem. I don't have the linux-generic (meta-ish) package installed somehow... Leading down the line of dependencies, I don't have the linux-image-extra package installed for my current kernel version. The b43 kernel module is in the linux-image-extra package. I'll install it now and update.

Yes, that was the problem... I didn't have the linux-generic package installed, therefor the linux-image-extra-[kernel version] package wasn't installed, therefor the b43 module was not available on my system. It's been a long day...
