  • What kernel do you need to install ? – Panther Mar 15 '12 at 21:38

I'd probably look at pre-built versions of the Kernel before jumping into compiling your own. The Mainline Kernel PPA should be your first port of call. Pick a version, install the package and reboot. If it works: awesome. If everything explodes, just select an older version from Grub and remove the package once you're booted up.

If you do want to follow the dark path of compiling your own kernel, I've written a few answers over the years that might help point you in the right direction.

They're old posts but everything in them should still apply today.


Maybe you just try to install a new kernel with apt-get? Try apt-cache search linux-image in order to find a new kernel package. Install it with apt-get install <package name> afterwards and reboot.

If you are not logged in as root, you should place a "sudo" in front of every command listed here. Is this information useful for you?

  • This will not get you a "newer" kernel, just the latest version for in the currently selected repository. Ubuntu doesn't tend to push major Kernel updates to old versions of Ubuntu. – Oli Mar 15 '12 at 21:45

It will be easier for you to install a mainline kernel from here:

How can I install a newer kernel?

Your best option may be to install 12.04. Be warned it is in beta at the moment, you might want to wait for the release.
