Solving the Permission Denied Error on Your Debian Web Server


Are you experiencing a “Permission Denied” error on your Debian-based web server? This common issue is particularly frustrating since it often occurs when you’re diligently working on a project, only to be stopped in your tracks. Luckily, I’m here to provide a helping hand. In this article, we will discuss what this error means, what causes it, and of course, how to resolve it.

Understanding the Permission Denied Error

The “Permission Denied” error essentially communicates that the user account you’re currently using doesn’t possess the necessary rights or permissions to execute a particular operation. This may be due to the user not being in the appropriate user group that has the required permissions, or the file or directory you’re trying to access has its permissions set in a way that’s preventing you from accessing it.

Solving the Error

The solution to this issue often involves adjusting the permissions of the file or directory so that your user account has the ability to carry out the requisite operation. Here is where ‘chmod’, a Linux/Unix command which alters file or directory permissions, comes into play.

1. Identifying the Problem

You first need to identify which file or directory is causing the permission issue. If running the command followed by the file path results in the “Permission Denied” error, then the problem file or directory has been identified.

2. Using Chmod to Solve the Problem

Open your terminal and type the following command:

sudo chmod 755 /path/to/your/file

This command changes the permissions of the file, allowing the owner to read, write and execute, while others can only read and execute.

3. Using Htop for Monitoring

Although ‘htop’ is not directly responsible for fixing permission issues, it’s a powerful tool for monitoring your system activities in real-time. By using it, you can ensure your changes haven’t disrupted any system processes or caused any unwanted performance issues. Navigate to htop by typing ‘htop’ in your terminal:



Resolving the “Permission Denied” error requires an understanding of Linux permissions and groups. By using the example commands provided in this post, you should be able to grant correct permissions to your files or directories and continue your work undisturbed.
