Is available 22.214.171.124 kernel for natty? How to upgrade?
You will need to install the kernel yourself:
Browse to the following location on Launchpad - link is below.
If you have a 64bit system download the two amd64.deb files.
If you have a 32bit system download the two i386.deb files.
In addition download the "_all.deb" file.
then install the downloaded debs
Then update your grub
You can Try:
KernelCheck is a graphical user interface program designed to make the kernel-compiling process as easy as the click of a button. A kernel is the base of any operating system – in our case, the Linux operating system. KernelCheck will fetch the latest information from http://www.kernel.org, which hosts the source packages for the Linux kernel, and ask the user which one they would like to compile into a .deb package (with the option of installing the kernel after the compilation).
This automated process is a fork of AutoKernel by Robert Wolterman (xtacocorex), Timothy Janssen (mentok), and Kristof Verbeken (PingunZ). KernelCheck is currently licensed under the GNU Public License version 3.
At the moment, KernelCheck is only supported on Debian-Based platforms. Some of these include Debian, Ubuntu (or any derivatives), Mint, etc. RPM and Slackware based are planned to be supported in the future.
Compiling a kernel under Ubuntu (even with the command line) is quite easy:
Just install the kernel-package package (:D):
and then download the kernel sources from http://kernel.org (under the "Latest Stable Kernel" heading) to a working directory, such as
to change to your working directory. For the next two steps, it's a good idea to open your file manager, so you can see the names of the files and folders easily. Now, you need to extract the archive you downloaded. You can either run the command below or right click the file and click "Extract."
Now, change to the directory that was created when you extracted the source archive.
Next, you need to copy the kernel configuration. 99% of the time, Ubuntu's default configuration will work just fine.
Finally, to compile the kernel, just run: [Note: CONCURRENCY_LEVEL should be set to the number of processor cores + 1. It will speed up the compile time a lot]
