software installation - Error get while installing ardupilot on virtualbox ubuntu 14.04.3

I want to implement ardupilot. I installed ubuntu-14.04.3-desktop-64 bit version via VirtualBox on windows8.1 on D drive and username is jaydeep.

Still this all fine. Now as per above link the first thing is, Download ardupilot, so I open terminal in ubuntu and run (without "sudo apt-get install" its gives error and suggest to use this, so append this code before actual command )

sudo apt-get install git clone git://github.com/diydrones/ardupilot.git

jaydeep@jaydeep-VirtualBox:~$ sudo apt-get install git clone
git://github.com/diydrones/ardupilot.git

[sudo] password for jaydeep:

'git://github.com/diydrones'

jaydeep@jaydeep-VirtualBox:~$

I can not figure it out. So how to resolve the error.

Well, the command that you have typed has a little typo. Here's the command to install git:

sudo apt-get install git

And to clone the git repository, you have to type the command:

git clone git://github.com/diydrones/ardupilot.git

EDIT: If you want to combine the commands then, type:

sudo apt-get install git && git clone git://github.com/diydrones/ardupilot.git
