17.3.2. Updating software with Yum

To update the generic package my-package to the latest version, type: su -c 'yum update my-package' Enter the password for the root account when prompted.

New Software Versions Require Reloading

If a piece of software is in use when you update it, the old version remains active until the application or service is restarted. Kernel updates take effect when you reboot the system.

Kernel Packages

Kernel packages remain on the system after they have been superseded by newer versions. This enables you to boot your system with an older kernel if an error occurs with the current kernel. To minimize maintenance, yum automatically removes obsolete kernel packages from your system, retaining only the current kernel and the previous version.

To update all of the packages in the package group PackageGroup, enter the command: su -c 'yum groupupdate "PackageGroup"' Enter the password for the root account when prompted.

Updating the Entire System

To update all of the packages on your Fedora system, use the command: su -c 'yum update' Enter the password for the root account when prompted.
