Install Softwares With Dependencies Without Internet

Debian Systems like Ubuntu and others’ software packages has the extension .deb. With the file, you can install softwares on your system. While you click the “Install” button on Ubuntu Software Center or on Synaptic Package Manger, what the system actually do is downloading the .deb file from the server and installing it. These .deb files are installed using the dpkg software. It’s not necessarily required for you to have internet to install softwares, but if you don’t have the dependencies of the software, internet is required for the software to download and install it.
