However when you are that busy, you might a minimum of make the effort to establish automated updates, so they do occur routinely. After all, you do not want to lose out on crucial security spots, efficiency enhancements and new functions.

With Rocky Linux, there’s an extremely handy tool you can set up and use for automating those updates. This tool allows you to configure updates for routine and even security updates.

Let’s get this software application set up and set up.

What you’ll require to make it possible for automated updates on Rocky Linux

To make this work, you’ll require a running instance of Rocky Linux and a user with sudo opportunities. I’ll demonstrate this on Rocky Linux 9, however this will deal with previous iterations. That’s it. Let’s get this up and running.

How to install the necessary software application

Visit to your circumstances of Rocky Linux, and open a terminal window. From the terminal, set up the necessary software application with the command:

sudo dnf set up dnf-automatic -y

That’s it for the setup of software.

How to set up dnf-automatic

The dnf-automatic bundle has a single configuration file, where you can personalize what updates are run. Open this file with the command:

sudo nano/ etc/dnf/automatic. conf

You must already see a number of predefined setups. After a fast scan of the file, you’ll also see that automated updates are disabled by default.

The default configuration is set up to immediately download the updates however not apply them. The download_updates choice need to be set to yes. Keep that as is. However, the apply_updates line is set to no by default. Modification that line, so it looks like this:

apply_updates = yes

Next, we require to set this up, so update info is sent out to MOTD (message of the day), which will notify you of any updates that have been used when you visit. For that, search for the line:

emit_via = stdio

Modification that to:

emit_via = motd

You will likewise discover, near the top of the file, a line that looks like this:

upgrade_type = default

If you don’t wish to install the default updates, which covers all plans, you could opt for only utilizing dnf-automatic to install security updates. For that, change the upgrade_type line to:

upgrade_type = security

Save and close the file.

How to allow the dnf-automatic timer

With dnf-automatic set up, you understand how to enable it via systemctl. To do this, release the command:

sudo systemctl enable– now dnf-automatic. timer

The default timer is set up, so updates will be applied at 6 a.m. every day. If that’s not a good time for your organization, you can alter it by opening the dnf-automatic. timer file with the command:

sudo vim/ etc/systemd/system/ dnf-automatic. timer

Because file, look for the line that starts with:


Say you wish to change those updates to run at 1:00 a.m. every day. For that, the line would look like this:

OnCalendar=*-*-* 01:00

You might also wish to change the randomized hold-up, which is set to 60 minutes, and make dnf-automatic to perform at a various time every day. To disable that, change the line:

RandomizedDelaySec = 60m


RandomizedDelaySec = 0m

Conserve and close the file. Then, reload the Systemd daemon with:

sudo systemctl daemon-reload

To verify the new setting, concern the command:

systemctl list-timers

In the output, you ought to see a listing comparable to this:

Tue 2022-10-11 01:00:00 EDT 14h left n/a n/a dnf-automatic. timer dnf-automatic. service

There you go. Automatic updates are now established for Rocky Linux. This is a great method to guarantee you don’t miss out on a day of updates for your RHEL-based os.
