I have to install b43-fwcutter to my Ubuntu 14.04 for wireless. When I do

sudo apt-get install b43-fwcutter

it says:

media change: please insert the disc labeled
'Ubuntu 14.04.1 LTS _Trusty Tahr_ - Release amd64 (20140722.2)
in the drive '/media/cdrom/' and press enter

but I have no CD. I installed Ubuntu using my USB Flash Memory. I tried to plug USB back but it didn't help.

So how can I install b43-fwcutter to my Ubuntu 14.04

  • Did you enable a cd/your installation media as software source in your system configuration? – Byte Commander Jan 24 '15 at 01:11
  • Yes I did enabled. So I disabled and removed from sources.list and everything works perfectly. – emreaydin149 Jan 24 '15 at 02:54

  • Both firmware-b43-installer and b43-fwcutter can be installed from either Synaptic Package manager or (I think) Ubuntu software center. But you need to begin with finding out what installers/ firmware are really appropriate for your driver. I have an answer here. http://ubuntuforums.org/showthread.php?t=2272677 It refers to other answers on the subject. – Dora Smith Apr 12 '15 at 03:04

Instead, I suggest:

sudo apt-get update
sudo apt-get install firmware-b43-installer
