Fedora includes a tool, dnf-automatic, which supports several modes of update automation: 
do not apply, notify admin, apply and notify admin, apply without notification. In particular, alternatives 2 and 3 are definitely worth considering. A general principle might be: Alternative 2 is the minimum choice for almost any system, alternative 3 is not at all suitable for critical systems that must not fail under any circumstances.

We recommend installing at least alternative 2:
[source,]
----
[…]# dnf install dnf-automatic 

[…]# vi /etc/dnf/automatic.conf
##emit_via = stdio
emit_via = email
##email_from = root@example.com
email_from = root@host.example.com
##

[…]# vi /etc/aliases 
...
# Person who should get root's mail
#root:        marc
root:         real@address.for.root

[…]# newaliases
[…]# systemctl enable --now dnf-automatic-notifyonly.timer
----

If you want to automatically install, activate the corresponding timer instead.
