A 500 Internal Server Error on Ubuntu typically indicates a problem with the server-side code, such as PHP, Python, or Node.js. Common causes include syntax errors in scripts, database connection issues, insufficient file permissions, resource limits (memory, CPU), or misconfigured server settings (like .htaccess for Apache). It's a generic error, meaning the server couldn't be more specific about the problem.
