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!
