Hi, I installed ubuntu server on a mac mini late 2012, and I have now (as expected) a problem with the firmware for the Broadcom network adapter / wifi card.
I could install those firmware quite easily with the package firmware-b43-installer but I obviously cannot use apt to download and install this package.
Then I thought to manually download the package from another computer and install it manually in Ubuntu. I saved the .deb into a USB stick and tried to install it, but this package depends on other packages that are not installed on the machine.
Then I thought “ok, I’ll do the same for the dependencies and I will install the manually before install the firmware-b43-installer”.
The problem is, of course, that also those packages depends on something else.
I don’t think is a good idea to go down into the dependency hole and look manually for all the depndendencies of the dependencies… there is a more efficient way to do this? There is a way to download a package with its recursive dependencies?
Or somebody installed already Ubuntu (or a debian based distro) on a mac mini with Broadcom chip that can put me on the right direction?
Thanks a lot.
- If you have an android phone, plug it into the macmini via usb, connect to wifi and enable usb tethering. - Amazing. It worked, thanks a lot 
- +1 Happy usb tethering user here. 👍 
- iPhones work too 
 
- Copying this package over USB will not work anyway, even if you get all the dependencies, since - firmware-b43-installeris just a script that downloads the firmware (probably because it is illegal for Debian/Ubuntu to redistribute this firmware because of the license).- You need internet. You’ll need to use a different network device for this, or use a phone as the other person said. - Or you can copy the firmware files over by hand, from a different Ubuntu/Linux computer. They should be under - /usr/lib/firmware/b43.- Right. I solved using the connection of my phone 
- Here is a manual on how to obtain firmware without using the script. 
 
- A quick search tells me that mac mini’s have ethernet. Are you able temporarily connect that way to fetch the wifi drivers? - Unfortunately also the ethernet connection wasn’t detected. I solved using my phone in USB tethering 
 
- One approach here is the Ubuntu CD/DVD images. You can (could?) use the disk as a package source for - aptto install from.
- The Linux mint live installer comes with the bcmwl-kernel-source package which will allow you to install it. It worked on my 2013 MacBook Pro which uses a Broadcom chip

- deleted by creator - This is incorrect, that firmware is not included in the installer (for legal reasons, probably). - firmware-b43-installeris just a script. It downloads some driver from a website and extracts the firmware blobs from that driver using another utility called- b43-fwcutter. The package description for that reads:- Description: utility for extracting Broadcom 43xx firmware - This package provides a tool for extracting BCM43xx wireless chip firmware from Broadcom’s proprietary driver files. - It is used by the firmware-b43(legacy)-installer packages as part of the automated process of downloading and installing firmware.
