Here are quick steps to install toolchain from this PPA on Ubuntu before 14.04:

Step1: Inside Ubuntu, open a terminal and input

       "sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded"

Step2: Continue to input

       "sudo apt-get update"

Step3: Continue to input to install toolchain

       "sudo apt-get install gcc-arm-none-eabi"

[...]

!!! If you are using Ubuntu 14.04 and later, please be careful because

there are packages with same name but produced by Debian and inherited by

Ubuntu. Simply follow the above 3 steps, you may end up with 

gcc-arm-none-eabi from Ubuntu. So to install gcc-arm-none-eabi from ARM,

steps are:

1). sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi

2). sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded

3). sudo apt-get update

4). sudo apt-get install gcc-arm-none-eabi=4.9.3.2014q4-0trusty12

    or

    sudo apt-get install gcc-arm-none-eabi=4.9.3.2014q4-0utopic12

Meanwhile we are working with Debian to consolidate and unify this toolchain.
