This short walkthrough describes how to install the Ubuntu Linux Kernel 3.19 (server and desktop/client) 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. The general packages are available for 32 bits systems (I386+) and 64 bits (AMD64) and both as low latency.

Installation Guide (GUI)

1. Download the kernel headers package:
   
   http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-headers-3.19.0-031900_3.19.0-031900.201502091451_all.deb
2. And the appropriate package for your system
   • AMD64:
     
     http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-headers-3.19.0-031900-generic_3.19.0-031900.201502091451_amd64.deb
   • I386:
     
     http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-headers-3.19.0-031900-generic_3.19.0-031900.201502091451_i386.deb
3. And the accompanying compiled kernel image
   • AMD64:
     
     http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-image-3.19.0-031900-generic_3.19.0-031900.201502091451_amd64.deb
   • I386:
     
     http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-image-3.19.0-031900-lowlatency_3.19.0-031900.201502091451_i386.deb
4. Install the files in the same order as downloaded above. So first install the headers (2 files) and finally the image (1 file).
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 3.19 branch and 3.20 release candidates in comments below.
