This section describes how to use the DNF Automatic application to automatically:

* Download and install any new updates
* Only download the updates
* Get notified about the updates

== Procedure

. Install the [package]_dnf-automatic_ package:
+
----
sudo dnf install dnf-automatic
----

. Edit the [filename]`/etc/dnf/automatic.conf` configuration file as needed. See the https://dnf.readthedocs.io/en/latest/automatic.html[DNF Automatic] documentation for details. 

. Enable and start the `systemd` timer:
+
[literal,subs="+quotes,attributes"]
----
sudo systemctl enable --now _timer_
----
+
Replace `_timer_` with one of following ones depending on what action you want to do:
+
--
* `dnf-automatic-install.timer` to download and install packages
* `dnf-automatic-download.timer` to only download packages
* `dnf-automatic-notifyonly.timer` to only get a notification using configured emitters in the [filename]`/etc/dnf/automatic.conf` file.
--
+
For example:
+
----
sudo systemctl enable --now dnf-automatic-install.timer
Created symlink /etc/systemd/system/timers.target.wants/dnf-automatic-install.timer → /usr/lib/systemd/system/dnf-automatic-install.timer.
----

. Ensure that the timer has been successfully enabled and started:
+
[literal,subs="+quotes,attributes"]
----
sudo systemctl status _timer_
----
+
Replace `_timer_` with the timer from the previous step, for example:
+
----
sudo systemctl status dnf-automatic-install.timer
