I am trying to install Ubuntu 14.04 server on a machine via USB. The machine only has a wireless connection and needs the wl driver (proprietary Broadcom STA wireless driver). Without this driver, the network detection process of the installation fails.

On this machine, I can install Ubuntu desktop via USB by booting the USB, running the following commands, then running the installation program.

sudo mkdir /cdrom
sudo mount /dev/sdX1 /cdrom
sudo dpkg -i /cdrom/pool/main/d/dkms/dkms*
sudo dpkg -i /cdrom/pool/restricted/b/bcmwl/bcmwl-kernel-source*

However, there are two problems when I try to install from the Ubuntu 14.04 server USB:

  1. The dkms and bcmwl-kernel-source packages are not included with the server ISO. This is not a big problem since I can add these to my USB.
  2. There is no dpkg program in the server installation shell.

How can I get my server installation media to have the additional kernel module wl?

Have you tried using Ubuntu Builder to add those three of these packages to the server iso? You can build your own server ISO with all of those packages, put the wireless driver .deb on the flash drive, and then install it with the server installation shell. –  Ian Hyzy May 13 at 18:08
    
have you tried installing linux-firmware-nonfree package? sudo apt-get install linux-firmware-nonfree –  user224082 May 13 at 19:55

@IanHyzy: The Ubuntu Builder has been discontinued. –  cubetwo1729 May 14 at 9:42
    
@DuminduMahawela: There is no apt-get in the server installer. –  cubetwo1729 May 14 at 9:43

You could use gparted to make a smallish extra partition on the usb. Set up the live boot on the large partition, then use APTonCD to get the driver you need and put it on the smallish partition. Install your server, mount and install from the smallish partition, then off you go. Ubuntu AptonCD Docs – Scott Goodgame 5 secs ago edit
