2. Installing the Deb format software

Sometimes we download Deb's software, like VirtualBox, so we can install it like this:

$ sudo dpkg-i virtualbox-4.3_4.3. the-98988~ubuntu~raring_amd64.deb Selecting previously unselected package virtualbox-4.3. (Reading Database... 237712Files and directories currently installed.) Preparing to unpack virtualbox-4.3_4.3. the-98988~ubuntu~raring_amd64.deb...Unpacking virtualbox-4.3(4.3. the-98988~ubuntu~raring)...Setting up virtualbox-4.3(4.3. the-98988~ubuntu~raring)...Adding group ' vboxusers ' (GID 127) ... Done.
