How do I upgrade the kernel?

Question

I have to upgrade to the new 3.7 kernel from 3.5 on Ubuntu 12.10 (3.5.0-24-generic kernel default) while also leaving the previously installed kernels and allow their optional selection during the boot process via grub2.

I'm not sure where to go from here. I found this: https://wiki.ubuntu.com/Kernel/MainlineBuilds , but am not sure which method / version is right. I also found this one Manual kernel upgrade and Ubuntu update so am a little worried that I might not install it correctly (from Ubuntu’s perspective). Also, do I want mainline or something else?

Thanks!

Answer 1

You manually download the kernel you wish to use from http://kernel.ubuntu.com/~kernel-ppa/mainline

You normally need just the kernel image, linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb for example.

You then install it with

dpkg -i linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb

and remove it with

sudo apt-get remove linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb

Please note, these kernels are intended for testing / development and come with no support

The mainline kernels builds are produced for debugging purposes and therefore come with no support. Use them at your own risk.
