Lauchpad Bug 285280
Ubuntu Forums Post

I applied a kernel update on October 15, 2008 which somehow didn’t have the updated nic-firmware package installed. Thus, my Intel 3945ABG wifi card stopped working…in the middle of work.
So after a couple minutes of research, I found this nifty little thread in the Ubuntu Forums. Following the instructions on the page, I indeed got my card to work.

Problem:

Upon the release of the next update they included the proper firmware in the package linux-firmware. This fails package updater and Update Manager. When I attempted to remove the package via Terminal I would get the following error:

$ sudo apt-get remove nic-firmware
Reading package lists… Done
Building dependency tree
Reading state information… Done
You might want to run `apt-get -f install’ to correct these:
The following packages have unmet dependencies:
linux-image-generic: Depends: linux-firmware but it is not going to be installed
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).

Fix:
Open the terminal and run the following:

# apt-get remove linux-image-generic

# apt-get remove linux-firmware

# apt-get remove nic-firmware

Then run updater and should update.

What was learned:
Packages have dependencies, and installing a dependency may not be the answer. You may need to work backwards. I had to remove all the packages that DEPENDED on nic-firmware before I could fix the problem. Seemed a bit backwards in my mind, but it worked.

So I am one of those kids who is always in the beta…of everything.

I decided to try the new version of Ubuntu (Intrepid Ibex). Install went pretty smooth, but when I went to open my Vbox Image it would just hang on spawning session.

The fix? Simple, reinstall VirtualBox or just run the recompile…

Download Package Here

or in the console enter:

sudo dpkg-reconfigure virtualbox-2.0

Problem Solved.
