How to Fix Chrome Failure in Selenium on Linux: A Headless Solution

Are you running into issues when trying to execute Selenium scripts on your Linux server? You're not alone! Many users encounter difficulties when setting up Selenium with Chrome in a headless environment, especially on servers without a graphical user interface (GUI).

In this guide, we’ll discuss a common problem: “Chrome failed to start,” and provide a straightforward solution to get your Selenium automation up and running smoothly. Let’s dive in!

Understanding the Problem

When you attempt to run a Selenium script on a server, especially one powered by Ubuntu without a GUI, you might encounter the following error message:

This indicates that the Chrome browser is not able to launch properly in headless mode. In many cases, the error is further compounded if you run your script as a root user, which may lead to a specific error:

This indicates that Chrome is refusing to run due to security concerns when executed under the root user account.

The Solution: Adding --no-sandbox

Step-by-Step Fix

Modify Your Selenium Code:
To resolve the issue, you need to make an adjustment in your Selenium script. Specifically, we need to add a new argument in the Chrome options. Here’s how you can do it:

Why --no-sandbox?

The --no-sandbox flag tells Chrome to run without a sandbox environment. This is particularly relevant when running on systems with certain restrictions, such as servers without a GUI or when the Chrome process is executed as root. While using this flag can expose your browser to potential security risks, for automated testing scenarios where the server is secured, it is an effective workaround.

Run Your Script:

After incorporating the above change, try running your Selenium script again. Make sure that Google Chrome is installed correctly and ensure that you have the right version compatible with your ChromeDriver.

Conclusion

With just a minor adjustment to your code, you can successfully run Chrome in headless mode on your Linux server using Selenium. If you experience similar issues in the future, remember to check for appropriate Chrome options that might affect the browser execution. Armed with this knowledge, you should be able to automate your web testing more effectively!
