红帽全球峰会第 5 章 Updating RHEL content
With the DNF software management tool, you can check if your system has any pending updates. You can list packages that need updating and choose to update a single package, multiple packages, or all packages at once. If any of the packages you choose to update have dependencies, these dependencies are updated as well.
提示
You can manage software updates in the Red Hat Enterprise Linux web console, which provides a graphical interface for DNF.
