The Technical Workflow:

1. Scheduled Execution: The workflow runs automatically each day at your preferred time
2. Secure Connection: It establishes a secure SSH connection to your Ubuntu server using your credentials
3. Package Checking: Executes standard Ubuntu package management commands to identify available updates
4. Smart Filtering: Analyzes results to determine if updates exist that require attention
5. Email Notification: When updates are detected, an email is automatically generated and sent via your SMTP service

The entire process runs silently in the background, requiring no manual intervention while ensuring you're always informed of necessary updates.
