I managed to get online through a Ethernet to USB adapter, but I still need help in having the WiFi in my new Ubuntu 17.10 installation finally work.

I tried downloading the driver (with the other 3 AMD64 dependencies),as described in Installing Broadcom Wireless Drivers but I get the following error.

Ubuntu is running on a SDHC Card on my MacBook Pro (Retina, 15-inch, Mid 2014) 2.5 GHz Intel Core i7.

Please help!

The terminal error I get

The procedure I followed

  • You're missing all the other build dependencies for GCC, etc. that dkms needs. That's a very complex web of packages you'll need to download and install, and might not be the easiest thing in the world to do... – Thomas Ward Mar 07 '18 at 15:16
  • thanks a lot Thomas for your reply. How is it possible that I'm missing all these packages? I installed the normal Ubuntu 17.10 image file following all the directions on the Ubuntu website. – Akko Mar 07 '18 at 20:43
  • the Ubuntu images do not contain the compiler and software-building-dependencies (aka build-essential in an apt-get install command, which in turn relies on the entire tree of compiler dependency packages) by default. That's why you're missing the dependencies of dkms, including but not limited to gcc, make, etc. which you need to compile with. I hate to ask but is there any reason you can't, say, connect to an Ethernet port for a short while on this machine to install the drivers and stuff? – Thomas Ward Mar 07 '18 at 20:44
  • Unfortunately, my macbook has no ethernet port. Unless there's a way to connect ethernet through the USB or thunderbold ports, I'm out of luck. Would getting a USB Wifi stick to download them work or would I need another driver for that? – Akko Mar 07 '18 at 20:47
  • You would probably need a driver for that. You might be able to get one of those USB Ethernet adapters and use that, but I'm not fluent in Mac hardware enough to say what would or wouldn't work. (I got a cheap one off of NewEgg a while back for my laptop, it's worked in all my systems so far) – Thomas Ward Mar 07 '18 at 21:08
  • Well, I guess it would come down again on wether Ubuntu has the driver for the USB Ethernet Adapter installed or not...am I wrong? – Akko Mar 07 '18 at 22:19
  • Hi again Thomas, the USB Ethernet Adapter fortunately didn't require any additional driver. So I'm online now but could you please tell me specifically how to proceed to download and install the "very complex web of packages" I need to have the WiFi work? – Akko Mar 10 '18 at 14:58
