18.1. システムの更新

The Fedora Project releases updated software packages for Fedora throughout the support period of each version. Updated packages add new features, improve reliability, resolve bugs, or remove security vulnerabilities. To ensure the security of your system, update regularly, and as soon as possible after a security announcement is issued. Refer to 「Subscribing to Fedora Announcements and News」 for information on the Fedora announcements services.
An update applet reminds you of updates when they are available. This applet is installed by default in Fedora. It checks for software updates from all configured repositories, and runs as a background service. It generates a notification message on the desktop if updates are found, and you can click the message to update your system's software.
To update your system with the latest packages manually, use Update System:

  2. To review the list of updated packages, select Review.
  3. Click Update System to begin the update process.
  4. If one or more updates require a system reboot, the update process displays a dialog with the option to Reboot Now. Either select this option to reboot the system immediately, or Cancel it and reboot the system at a more convenient time.
  5. If a reboot is not required the update will conclude with a dialog that indicates that the System Update Completed and all selected updates have been successfully installed as well as a button to Close Update System
To update packages from the command-line, use the yum utility. Type this command to begin a full update of your system with yum:
su -c 'yum update'

Network Connection Required

Ensure that your system has an active network connection before you run the Update Software tool, or the yum utility. The update process downloads information and packages from a network of servers.
If your Fedora system has a permanent network connection, you may choose to enable daily system updates. To enable automatic updates, follow the instructions on the webpage
