There are several ways to install software in Ubuntu, some are easy like the Software Center, and are a bit advanced like Synaptic Package Manager, and you can download a DEB file form the Internet and install it (not recommended)..

But what happens when you want to transfer a lot of software to another computer, or install them on your freshly installed Ubuntu?

You can download them one by one of course :/ but you don’t want to do that, don’t you?
That’s why you are here 😉

My way is very simple and requires a little knowledge of your system.

•  First copy the software you need from this directory on your computer:
  “/var/cache/apt/archives”

• Copy the ones you need or all of them if you like

• Paste them in a folder in your system partition (Where Ubuntu is installed), like your home folder.

• Now open Synaptic Package Manager and enter your administrator password.

• When it loads up navigate to File Add downloaded packages

• Browse to the folder Archives you just copied form the old computer

• Wait for it to add the packages, and here you have them.

• It will install the changes automatically (Batch install your packages). 

As easy as that 😀

And the sweet part is: If you previously backed up your computer and restored it after adding the packages you will restore the settings as well 😀

Here you have it 😀 I hope you find this useful  🙂
P.S: I tested it on Zorin OS 7, so it should work on Ubuntu 13.04 with no problem.
