Install additional software
The Ubuntu development team has chosen a default set of applications that we think makes Ubuntu very useful for most day-to-day tasks. However, you will certainly want to install more software to make Ubuntu more useful to you.
To install additional software, complete the following steps:
Unless you are installing software from a local source, make sure that you have a working Internet connection.
Click on the Ubuntu Software Center icon in the Launcher, or search for Software Center in the search bar of the Dash.
When the Software Center launches, search for an application, or select a category and find an application from the list.
Select the application that you are interested in and click Install.
You will be asked to enter your password. Once you have done that the installation will begin.
The installation usually finishes quickly, but could take a while if you have a slow Internet connection. When it has finished, your new application will be ready to use; most applications can be accessed from the Applications menu.
For more information about using the Ubuntu Software Center, consult the Ubuntu Software Center Manual.
