Comment 4 for bug 1383515

Something broke in the past and affected the current installation. Please try these commands in order to remove the bbswitch module and continue the installation through apt:

    sudo dkms remove -m dkms -v 0.7 --all
    sudo apt-get install -f

Now you should see bbswitch when running this command:

    dkms status

If not, reinstall bbswitch:

    sudo apt-get install --reinstall bbswitch-dkms
