I always configure Webmin to automatically install security updates and notify me via email (Mailgun guide) if there are other package updates. This keeps your VPS or dedicated server running the latest security patches to prevent hacks. This is a super short tutorial for configuring automatic security updates with Webmin on Linux.
Configure Automatic Security Updates with Webmin
Log in to Webmin using your IP address of the VPS or dedicated server on port 10000.
Navigate to System > Software Package Updates
For Check for Updates on schedule select Yes, every day
For Action when update needed select Install security updates
That is it, Webmin is now configured to automatically install security updates at midnight. If you have Webmin configured to send email via its built-in configurable SMTP mailer or through postfix then you will receive an email when there are other package updates available.
