Comment 3 for bug 499513

Got the same problem on 14.04:
ii aircrack-ng 1:1.1-6 amd64 wireless WEP/WPA cracking utilities
ii gcc 4:4.8.2-1ubuntu6 amd64 GNU C compiler
ii gcc-4.8 4.8.2-19ubuntu1 amd64 GNU C compiler

The problem is that in /usr/sbin/airdriver-ng we have this:

#check if gcc version matches the kernel gcc version
    gccvers="`$GCC --version | head -n 1 | sed 's/^[^ ]* [^ ]* \([2-4]..*\)$/\1/'`"
    ret="`cat /proc/version | grep "$gccvers"`"

    if [ x"$ret" == x ]
    then
        echo "Your current GCC version doesn't match the version your kernel was compiled with."
        echo "The build modules will probably not load into the running kernel."
    fi

but

root@dell:~# gcc --version | head -n 1 | sed 's/^[^ ]* [^ ]* \([2-4]..*\)$/\1/'
4.8.2-19ubuntu1) 4.8.2
root@dell:~# cat /proc/version
Linux version 3.13.0-24-generic (buildd@panlong) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014

so the version check fails although the versions match.

Changing the sed to 's/^[^ ]* [^ ]* \([2-4]..*\)).*$/\1/' gets you past that point, but then (on kubuntu 14.04) if you don't have the kernel sources in place you hit

1. Getting the source...Couldn't find the correct driver file: linux-3.3.13.0-24-generic.3.13.0-24-generic.tar.bz2

because the script can't handle the 3.xx.x kernel version string and looks for
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-3.3.13.0-24-generic.3.13.0-24-generic.tar.bz2

"v2.6" is hardcoded in the script, so it won't work for 3.x source fetching.

Then looking furhter in the script I found that at least for my case (broadcom chipset), it probably will fail the kernel patching, because the script also has the patch for kernel 2.6 hardcoded:

DI_PATCHFILE[$i]="bcm43xx-injection-linux-2.6.20.patch"

At this point I conclude that aircrack-ng was poorly (or not at all) integrated to ubuntu, so I'm going to look for a live dvd pentest distro for my tests.
