New kernels

bigjohn · 06-21-2006, 02:28 PM

In the past (with other distros), when I've installed a new kernel version, and checked that it's working OK, I've dumped the older one(s).

where do they live, in K/Ubuntu ? I couldn't find anything in /usr/src/linux or similar?

just run apt-get remove kernel-image-*version*

If you are going to remove a kernel that was installed by a package manager, then remove it with a package manager and not manually. If you remove it manually you may have problems because the package managers database will still register it as installed.

Nope. Didn't work. It (apt) couldn't find any kernel-image-any version. Any other suggestions ?? Or might it be called something different ???

Debian kernels are named linux-image-{some-version}.

It is easiest to remove using synaptic. Go to System>Administration>Synaptic package manager. Scroll down to "linux-image-<names>" and see what kernels are installed. Click on one you don't like and select "mark for complete removal". It will free up quite a bit of disk space if you have a number of unused kernels.

which is why I couldn't find it under the synaptic listing, I was looking for "kernel-version-xxxxxx" which is where the 2.4 stuff seems to be listed, as opposed to the "linux-image-xxxxxxxxx" which is where it was all the time, just waiting for me to "click dem lil' ole boxes"

somewhat conveniently modifying my /grub/menu.lst as well.

TVM for the advice.

I hope i am not writing to late. Now, since i was looking for a way to remove some entries too, and free up some disk space, i used the search tool and ended up here. I am using kubuntu at the moment and i don't have synaptic, and apparently the apt way doesn't work. So how can i do this with kubuntu?

You can use apt in Kubuntu. If you don't have synaptic installed, you can install it from a terminal with:

Code:

sudo apt-get install synaptic

Then you can view and remove kernels as described above.

Kubuntu has Aptitude as the front end. It should be as good as Synaptic, I guess. I haven't used aptitude actually.

trebek · 12-07-2006, 01:50 AM

Isn't there a manual way to do this? Please don't get this question the wrong way, i just want to be able to do it using the console instead of having an application do it for me, for learning purposes. I really wanna know how to do it manually. Thanks in advance.

lin_user2004 · 12-07-2006, 02:45 AM

If you know the kernel version no. then type this in the terminal

Code:

sudo apt-get remove kernel-image-<exact version no>

And in my previous reply I wrote Aptitude as the front end. I am sorry, it's adept and not aptitude.

m_yates · 12-07-2006, 06:54 AM

Sure there is a manual way...first, besome root:

Code:

sudo su

Then as root run:

Code:

dpkg --get-selections | grep linux-image

The output will show you what kernels are installed. Pick the one you want to remove:

Code:

dpkg -P linux-image-2.6.17-26-386

The "-P" option will purge everything associated with the package, including configuration files. Good luck!

I did find adept there, but i am a big fan of apt-get, i'll try it up this way. I do want to get some more space; i got like 5 images and 4 i am currently not using. Just add up the space i'll be freeing with these steps.

I'll look into dpkg command. I tried it in Fedora 4 and that command is not available. I guess i'll install it or see a way around it.

Just so i know, quick question: is dpkg available on kubuntu? I am not at my house right now, i am at work, just wanted to know if this is so.

lin_user2004 · 12-09-2006, 10:43 AM

Yes dpkg is available on Kubuntu. In fact it will be available on any distro based on debian.
Fedora isn't based in Debian so it won't have dpkg.
