Fedora provides you with a complete operating system with a vast
range of capabilities, supported by a large community.
18.1. Updating Your System
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
Section 18.3, “Subscribing to Fedora Announcements and News” for information on the
Fedora announcements services.
A new update applet, called
puplet
,
reminds you of updates when they are available. The
puplet
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 the
Software Updater
:
-
Choose → → .
-
When prompted, enter the
root
password.
-
Review the list of updated packages. The package list displays
a double arrow next to any updates that require a system
reboot to take effect.
-
Click
Apply Updates
to begin the update
process.
-
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.
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'
Enter the root
password
when prompted.
Refer to https://docs.fedoraproject.org/yum/ for
more information on yum
.

Network Connection Required |
Ensure that your system has an active network connection before
you run the
Software Updater
, 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 https://docs.fedoraproject.org/yum/sn-updating-your-system.html.
