To Install / Upgrade Kernel 3.10.10, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

For 32bit

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.10-saucy/linux-headers-3.10.10-031010-generic_3.10.10-031010.201308291422_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.10-saucy/linux-headers-3.10.10-031010_3.10.10-031010.201308291422_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.10-saucy/linux-image-3.10.10-031010-generic_3.10.10-031010.201308291422_i386.deb

For 64bit

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.10-saucy/linux-headers-3.10.10-031010-generic_3.10.10-031010.201308291422_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.10-saucy/linux-headers-3.10.10-031010_3.10.10-031010.201308291422_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.10-saucy/linux-image-3.10.10-031010-generic_3.10.10-031010.201308291422_amd64.deb

Once done then run the following command:

sudo dpkg -i linux-headers-3.10.10-*.deb linux-image-3.10.10*.deb

Here are generic instructions that work on any version:

There's a lag between when a Kernel is released, and when it's available packaged in Ubuntu updates. If you need to run a current Kernel to test a bug fix or for some other reason, you'll have to download it yourself from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/

You'll need to match your Ubuntu version, and your 32 or 64 bit system type. Download those files to your /tmp partition using wget or something similar, and run:

sudo dpkg -i linux-*.deb

Optionally, to remove an old Kernel, find it's version number then run:

sudo apt-get purge linux-image-YYYYYY*
