How to remove the 2 old Linux kernel modules from kernels 3.0.0-19 und 3.2.0-26?

~$ man dkms

"'dkms remove [module/module-version]' removes a module/version combination from a tree.'

What is a "[module/module-version]", please?

Please notice:

I do not want to remove old Linux kernel modules tp_smapi from a tree but I'd like to remove old Linux kernel modules from my Ubuntu 12.04.1 computer.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
Why do you want to remove those modules? Which module-version is in use? You can see it with "modinfo tp_smapi" –  BuZZ-dEE Sep 4 '12 at 9:04

Maybe you should see this link; it has good instruction except perhaps the grub update.

Or, more safely, open the Ubuntu Software Center then search for Linux Kernel Image. Make sure to show the technical terms (click on "Show Technical Terms" located on the lower left of the screen).

Then update grub with the command:

user#: sudo update-grub

(# - root or administrative privileges)

Cheers! :)

This has been tried on 10.04, 11.10, and 12.10. However ... I do not guarantee you if it will preserve your modules!

List your kernels with

dpkg --list | grep linux-image

Then just

sudo apt-get purge [image name(s) from the list]*

On older versions of Ubuntu (not 12.04 onwards), you need to say "hi" to GRUB:

sudo update-grub2

On my 12.04 system, grub was automatically re-run, so no need to do the third step (sudo update-grub2). –  Fred Hamilton Sep 29 '12 at 23:00
    
some more cleanup: dpkg --list | grep linux-headers sudo apt-get purge [packagename from the list] –  key_ Feb 19 at 8:39

Actually an easier (for people who favor GUIs over command line) and apparently more thorough (it found and deleted header files "apt-get purge ..." missed) alternative is to just install Ubuntu Tweak.

Go to Janitor/System/Old Kernel, select it, and press "Clean".
