How to add Debian software repository

Software repository does not add when we install Debian Linux from CD/DVD without Internet connection. You can't update the Debian Linux without software repository. But you can add software repository later. Find a repository near your area. Download from remote server take long time to download updates.

You can find Debian software repository near your area by visiting Debian Source List Generator

In my experience, repositories from India is slow and so I make use Debian repositories from Japan. 

Add repository address to Debian

Open Applications > Accessories > Terminal 
Open sources file and add repository address.

leafpad /etc/apt/sources.list

Copy paste the lines to the file. Here is the repository from Japan,

deb wheezy main
deb-src wheezy main

deb wheezy/updates main
deb-src wheezy/updates main

# wheezy-updates, previously known as 'volatile'
deb wheezy-updates main
deb-src wheezy-updates main

Save and close the file. Update the sources list.

apt-get update

Install Indian fonts

India is a country rich with regional languages. You can install regional language fonts in Ubuntu. Apply following command in a terminal,

apt-get install ttf-indic-fonts

This font package include Malayalam, Hindi, Tamil, Kannada etc.

Malayalam Fonts
You can download and install various Malayalam fonts from Malayalam Computing website.
