6.5. Using Add/Remove Applications‌

The Add/Remove tool is the easiest to use and will enable you to install and uninstall many popular packages. You can search for the package or packages you want to install by simply searching a keyword such as 'email' or by looking through the given categories, selecting applications and choosing "Apply" to start the installation.

Note:

You need administrative access to use any package manager. Type the password for your user name

at the prompt. This means that applications can not be added / removed from your computer without your knowledge (and password).

Procedure 6.9. The procedure to add or remove software by using Add/Remove Applications is:

1. On the Applications menu, click Add/Remove.

2. The Add/Remove Applications dialogue box displays a list of applications. The check boxes against the applications that are already installed are pre-selected.

Note:

Many package names in Ubuntu are quite obscure, so the package manager will also look at

the package description when searching.

3. If you know the name of the package to be installed, you can type the name in the Search box. Otherwise, you can click the appropriate software category in the left pane and select the check box next to the required package in the right pane.

Nice to Know:

For more details about a package, click the package and view the bottom pane.
