Here’s How to Upgrade a Fedora 24 Linux to Fedora 25 via GNOME Software or DNF

Now, if you’re using the flagship Workstation edition, which uses the GNOME desktop environment, you should see a notification that tells you an upgrade is available. If this is the case for you, go ahead and click the notification, which will launch the GNOME Software graphical package manager. Even if you did not receive the upgrade notification, you can still open GNOME Software from your GNOME Shell interface, go to the Updates tab, and upgrade your Fedora 24 system to Fedora 25 by following the on-screen instruction. Check out the screenshot below to see how GNOME Software should look like before the upgrade operation.
