Chapter 16. Updating Red Hat Certificate System

For example:

dnf update

# dnf update

This downloads, verifies, and installs updates for Certificate System as well as operating system packages. You can verify the version number before and after updating packages, to confirm they were successfully installed.

To optionally download updates without installing, use the --downloadonly option in the above procedure:

dnf update --downloadonly

# dnf update --downloadonly

The downloaded packages are stored in the /var/cache/yum/ directory.
The dnf update will later use the packages if they are the latest versions.
