Update All Installed Packages

This section provides a tutorial example on how to update all installed packages on Linux systems using the 'dnf update' command.

If you install a Linux system from a distribution ISO image, some system and software packages included in the image might be outdated. You can follow this tutorial to check and update all packages currently installed on the system.

Run 'dnf update -y' command to update all installed packages without prompting confirmations.

herong$ sudo dnf update -y
