Download the latest from here:
The folders correspond to kernel versions and should also include the ubuntu version, for example I chose to update 11.10 (oneiric) from “3.0.0-14-generic” to “3.1.4”, this was in a directory called “v3.1.4-oneiric/“.
You’ll need 3 files (replace * with the kernel version you’ve downloaded):
For 64 bit systems (replace * with the kernel version you’ve downloaded):
For 32 bit systems (replace * with the kernel version you’ve downloaded):
Once you have the files, install them in the following order using these commands (of course, replacing the version number for the ones you’ve downloaded):
sudo dpkg -U linux-headers-3.1.4-030104_3.1.4-030104.201111281851_all.deb sudo dpkg -U linux-headers-3.1.4-030104-generic_3.1.4-030104.201111281851_amd64.deb sudo dpkg -U linux-image-3.1.4-030104-generic_3.1.4-030104.201111281851_amd64.deb
Once that’s done, reboot. Once you’re back use the following command to check that the kernel you’re using is the one you’ve just downloaded and installed!
