This short walkthrough describes how to install the Ubuntu linux kernel version 3.14  on without compiling.

This guide should work with the latest version of Ubuntu Linux and most Ubuntu-based distributions including Mint. The included kernel files have been compiled using the generic Ubuntu configuration.

Installation Guide (GUI)

1. Download the kernel headers package:
   
   http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/linux-headers-3.14.0-031400_3.14.0-031400.201403310035_all.deb
2. And the appropriate package for your system
   • AMD64:  http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/linux-headers-3.14.0-031400-generic_3.14.0-031400.201403310035_amd64.deb
   • I386: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/linux-headers-3.14.0-031400-generic_3.14.0-031400.201403310035_i386.deb
3. And the accompanying compiled kernel image
   • AMD64: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/linux-image-3.14.0-031400-generic_3.14.0-031400.201403310035_amd64.deb
   • I386: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/linux-image-3.14.0-031400-generic_3.14.0-031400.201403310035_i386.deb
4. Install the files in the same order as downloaded above. So first install the headers and finally the image.
5. In the terminal run:
   
   sudo update-grub
6. Reboot and select the kernel from the bootloader menu

I will post the latest version of the 3.14 branch and 3.14 release candidates in comments below.
