Unmet dependencies when I tried to free up unused kernels

I am running 12.04.

I read this https://askubuntu.com/a/90219/18876 as reference.

I checked all the one I have.

yeukhon@fubini:~$ aptitude search ~ilinux-image
i   linux-image-3.2.0-29-generic-pae     - Linux kernel image for version 3.2.0 on 32 bit

BB  linux-image-generic-pae              - Generic Linux kernel image

I think I am using 39?

yeukhon@fubini:~$ uname -a
Linux fubini 3.2.0-39-generic-pae #62-Ubuntu SMP Wed Feb 27 22:25:11 UTC 2013 i686 i686 i386 GNU/Linux

So I started purging as suggested in the reference.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-image-generic-pae : Depends: linux-image-3.2.0-40-generic-pae but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Now I don't know how to proceed, especially I don't want to mess up the computer. Ideas? Thanks.

Solution

I found My /boot partition hit 100% and now I can't upgrade. Can't remove old kernels to make room later. Basically, I followed his advise by [removing] old vmlinuz initrd, abi and System.map files individually until I got enough free space. I only need to delete the first two.

Then I do sudo apt-get install -f and finally use @Salem's little bash script to remove most of the old kernels. I kept the last two as suggested. Reboot at the end, and then if I do uname -a I will see the new kernel is now installed (in my case, that's 40).
