Common Pitfalls

Common mistakes when installing Nginx on Ubuntu include:

• Not running sudo apt update before installing, which can cause package not found errors.
• Forgetting to start the Nginx service after installation, so the server does not run.
• Not enabling Nginx to start on boot, causing it to stop after reboot.
• Running commands without sudo, leading to permission denied errors.

bash

Wrong (missing update and start):
apt install nginx

Right:
sudo apt update
sudo apt install nginx
sudo systemctl start nginx
