The most commonly used method to carry out the installation of additional packages in Ubuntu is the apt-get. The working mechanism of apt-get is very easy to understand, you specify the software package to install and it searches for that particular software from the Internet and if found, apt-get downloads it to your machine and installs it. APTonCD is a graphical tool which allows you to create one or more CDs or DVDs of all the packages you’ve downloaded via apt-get and thus it creates a removable repository that you can use on other computers. The main advantage of APTonCD is that you don’t need to download packages again if you are doing a fresh installation of your system, you can restore the previously installed programs easily. Lets see how we can install and use it in Ubuntu.
