ensure you choose the package for the actual program. Selecting each of the packages and reading the descriptions should be sufficient, and it should become obvious that the package needed to install the program is called frozen-bubble.

TIP If you already know the specific package name (maybe you read it on a web page, for example), a quicker method of searching is to ensure a package is selected in the main list, and to simply start typing the package name. This will automatically filter the list of packages according to what you type. 4.

Click the checkbox alongside the frozen-bubble entry in the list. Immediately, you will see a pop-up menu offering a variety of options. The one needed for installation is Mark for Installation.

Once you’ve made your selection, a dialog may appear explaining that additional packages need to be installed. These are the dependencies required for the program to work correctly. You should click the MARK button to add them to the list of packages to be installed. If you click CANCEL instead, the original package will be deselected.

NOTE While nearly all programs have dependencies, it’s not always the case that you will be prompted to install them, because they may already be installed on the system. If you don’t see a prompt to install dependencies then don’t worry—it’s unlikely anything has gone wrong. 6.

Now click the APPLY button on the toolbar. A summary dialog box will appear showing the packages that are to be installed (click the SHOW DETAILS button to see the complete list). Additionally, you’ll be told how much disk space the new application will take up. Assuming you’re happy with all of this, click the APPLY button in the dialog box to install the software.

Download and installation takes place automatically, usually in a matter of minutes. A confirmation dialog will appear at the end and, following this, you will find an icon for the new software on the relevant Applications or System submenu—in the case of Frozen-Bubble, the icon appears on the Applications Games menu.

TIP In addition to dependencies, some packages have a list of recommended packages, and sometimes a list of suggested packages too. These are non-essential add-ons that enhance the program’s features. For example, if you install a word processor, a thesaurus application might be a suggested package. You can install the recommended and/or suggested packages by 104 : Software Management
