[Bug 1293037] [NEW] Broadcom STA driver installed in live USB, but driver lost after installing Ubuntu in HD

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I downloaded the latest build of ubuntu 14.04, trusty-desktop-amd64. (2014-03-15)
Ubiquity 2.17.9
Apt 0.9.15.4ubuntu2

Booted it from a USB flash drive and installed the Broadcom STA, going
to "Software & Updates" -> "Additional Drivers".

It worked great! Then I installed Ubuntu in the hard drive, and the
installed version did not have the STA drivers.

I can easily see the proprietary driver is not installed:

# dmesg | grep b43

And there should be a wl.ko file in the dkms folder.
/lib/modules/3.13.0-17-generic/updates/dkms/wl.ko

but there isn't even dkms.

ok, then I thought, let's just install the driver again, but I can't, I
need a Ubuntu DVD. APT cannot see a USB flash drive as a CD/DVD, it
can't easily be added as a repository. (maybe I should open an issue to
APT too?)

So I tried the whole procedure 1 more time, and the same thing happened,
I'm able to reproduce the error.

I have the skills to install the driver without internet, I only need
the dkms and bcmwl-kernel-source deb files, but a lot of users can
struggle with it. Maybe this is not a bug, just a feature request, but
it would be really helpful.

Let me know if you need more information.

Thank you,

Arthur
