How do I install Libre 5.0.1 on Ubuntu 14.04. LTS

I downloaded the pack and extracted it. I then went to the folder and did sudo dpkg -i *.deb
The installation appeared to complete. I see no new Icons or any changes when I run the BASE and all is still the old version.

Put the following in terminal

sudo apt-get purge libreoffice-core

sudo add-apt-repository -y ppa:libreoffice/ppa

sudo apt-get update

sudo apt-get install libreoffice

And to install the help?

@Gilberto: install appropriate libreoffice-help- package.
