The Apache2 service on the system is currently masked and inactive (dead).
The Apache2 service has been masked, meaning it is explicitly disabled and cannot be started until it is unmasked. Masking is typically done to ensure the service is not accidentally started.
If you want to unmask and start the Apache2 service, follow these steps:
sudo systemctl unmask apache2
sudo systemctl start apache2
sudo systemctl enable apache2
sudo systemctl status apache2
If you intentionally masked Apache2 (e.g., because you're using another web server like Nginx), no further action is required. The system is configured this way for a specific purpose.
