Thankfully to community developers there are at least four ways to install software in Ubuntu. In this post I will describe the easiest ways to get some new application installed: using Synaptic Package Manager, Ubuntu Software Center, Gdebi and aptitude way (command line).
This is the graphical tool to fetch and install software through Ubuntu software channels also known as software sources. Synaptic Package Manager shows the list of software available in those sources and allows Ubuntu user to install in a few clicks.
1. Go to Ubuntu main menu –> Synaptic Package Manager and browse through categories to find necessary application or use Quick Search:
2. You can mark for installation many applications and install all of them by pressing Apply button — in a few minutes Ubuntu will download and install applications marked for installation as well as all necessary libraries and dependencies.
The easiest way to install software is using Ubuntu Software Center. This tool is extremely easy for Ubuntu newbies and makes it possible to install apps even easier than Synaptic Package Manager — just in one click.
1. Go to Ubuntu main menu and select Ubuntu software Center:
2. Browse through categories to find the application you’re going to install, here is an example:
3. Press Install button when ready to install selected application. While Ubuntu downloads and installs the software you can browse applications categories and put more applications into installation turn (select Get Free Software for this):
Ubuntu software comes as .deb binary packages which can be installed using graphical tool Gdebi or via command line (this is described a bit later in this post). Let’s imagine you’ve downloaded picasa_3.0-current_i386.deb package from picasa.google.com and stored it into your Desktop. Gdebi comes with Ubuntu by default and .deb files are associated with it from the beginning so just double click downloaded .deb package. Press Install button in opened window to proceed with the installation:
Aptitude is command line package manager meaning that you have to run it in terminal.
1. Go to Ubuntu main menu –> Accessories –> Terminal to open Gnome terminal window. In opened terminal window type sudo aptitude command and press return to start it:
2. Browse through applications and select some package pressing ‘+’ key on it:
In a few minutes Ubuntu will download and install selected software.
You can also install certain application using aptitude by command (realplayer is just an example):
sudo aptitude install realplayer
P.S. Here is the command to install downloaded .deb file in command line:
sudo dpkg -i someapplication.deb
