Software repository does not add when we install Debian Linux from CD/DVD without Internet connection. You can’t update the Debian
Linux is without software repository, but you can add it later. Find a repository near your area. Download from remote server take long time to download updates.
You can find Debian repository near your area by visiting Debian Source List Generator.
In my experience, repositories from Italy is slow and so I make use Debian repositories from Japan.
Add software repository address to Debian
Open Applications > Accessories > Terminal
Open sources file and add repository address.
su leafpad /etc/apt/sources.list
Copy paste the lines to the file. Here is the repository from Japan,
deb http://ftp.jp.debian.org/debian/ wheezy main deb-src http://ftp.jp.debian.org/debian/ wheezy main deb http://security.debian.org/ wheezy/updates main deb-src http://security.debian.org/ wheezy/updates main # wheezy-updates, previously known as 'volatile' deb http://ftp.jp.debian.org/debian/ wheezy-updates main deb-src http://ftp.jp.debian.org/debian/ wheezy-updates main
Save and close the file. Update the sources list.
