I followed the directions on Installing Ubuntu 12.10 on Macbook Pro Retina (10,1)
sudo apt-get update && sudo apt-get install b43-fwcutter wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 tar -xf broadcom-wl-5.100.138.tar.bz2 sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o sudo reboot
When i try to do step three I get:
tar: broadcom-wl-5.100.138.tar.bz2: Cannot open: No such file or directory tar: Error is not recoverable: exiting now
Even though I downloaded the file thrice in Firefox and even extracted it in the archive manager. I’m new to Linux but its going to be hard to learn something if I cant even connect to wi-fi. Please help.
