Apply the available updates:

$ sudo rpm-ostree upgrade

Due to the atomic nature of the OS, you will have to reboot into the new image to have the updates take effect:

$ systemctl reboot

The rpm-ostree utility keeps two deployments available. Both have an entry in the bootloader menu and the new updated entry with be the default. If necessary, you can choose the other entry to boot into the previous deployment.

The timeout for GRUB2 to display the menu is very short at only one second. Pressing the space bar or an arrow key when the menu appears will interrupt the timeout and allow you to choose another entry. The ENTER key will boot the selected image.
More information on managing upgrades and rollbacks can be found in the User Guide.
