Fedora Linux

localupdate rpm_file
-C	Runs the specified command from cache (doesn't contact each repository to check for updates).

5.3.1.2. Using yum with a GUI

Fedora Core also provides graphical tools for using yum . When updates are available for any of the packages on your system, an update icon (which looks like a cardboard box) will appear in the upper GNOME panel. If you place your mouse cursor over this icon, a tool tip message will appear showing the number of available updates, as shown in the upper-right corner of Figure 5-1.

The yum-updatesd service must be running to make the update icon appear. 

To install the available updates, right-click on the update icon and select Apply Updates (or select Applications>System Tools>Software Updater, or enter the command pup). You will be prompted for the root password, and then the window shown in Figure 5-1 will appear; click 'Apply updates' to install the updates listed.

 Fedora Core also provides a tool for graphically installing and removing software, named Pirut (pronounced 'pirate'). To start this program, select the menu option Applications>Add/Remove Software; you will be prompted for the root password. Pirut offers three main modes of operation, as shown in Figure 5-2; these modes are selected using the buttons on the left side of the window and permit you to search for a specific package (the top window in Figure 5-2), browse by package groups (middle window, along with the window that appears when you click on 'Optional packages'), or scroll through a list of all packages (bottom window).

If the browse-package-groups window looks familiar, you have a good memory. The same display is used for software package customization during installation. 

Select the checkbox in front of the packages that you wish to install, and deselect the checkbox of the packages that you wish to uninstall; then click Apply. After confirmation, the selected actions will be performed.

Fedora Extras also provides the Yumex tool, which provides an alternate graphical frontend to yum.

5.3.1.3. Adding repositories

Fedora Core ships with configuration files for the six repositories listed in Table 5-6 . The three prerelease repositories are disabled by default, and the rest are enabled.

Table 5-6. Fedora Core repositories

Repository	Enabled by default	Description
base	Y	Fedora Core base packages (same as CD/DVD)
development	N	Prerelease Fedora Core packages (also known as 'Rawhide')
updates-released	Y	Updates to Fedora Core packages
updates-testing	N	Prerelease update packages
extras	Y	Add-on software for Fedora

The repositories are configured by files in /etc/yum.repos.d . Here is the content of the Fedora Extras file /etc/yum.repos.d/fedora-extras.repo :
