Comment 22 for bug 1392460

I am trying to follow the instructions for installing these kernels, but there is clearly something wrong.

Firstly the installs all fail with the following known bug:

bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu1: bcmwl kernel module failed to build [error: macro "alloc_netdev" requires 4 arguments, but only 3 given] Edit

    Ubuntu
    “bcmwl” package
    Bugs
    Bug #1358966

This is obviously a simple error which could be fixed in a minute. I suspect it is the failed installation that causes the resulting system boot kernel panic because of a missing init.

Secondly when I issue the specified command in the web page to remove the 3.18 headers and kernel the following happens:

sudo apt-get remove linux-headers-3.18* linux-image-3.18*

In other words the command removed every kernel EXCEPT the broken 3.18 kernel! So the partition I am using to test 3.18 is now unbootable. I have had to reinstall Ubuntu 14.10 from the DVD.

Please fix the installation of 3.18 and get back to me. I will not try anything more until I get a clean installation.
