If you have encountered the error "Running as root without --no-sandbox is not supported" while using applications such as Electron or Google Chrome, you're not alone. This error typically occurs when you try to run these applications as a root user without the required sandbox flag. In this guide, we will walk you through a step-by-step process to resolve this issue.

Understanding the Error
Running applications as the root user can pose a potential security risk, as it grants the application complete access to your system. To mitigate this risk, developers use a security feature called a sandbox that isolates the application from the rest of the system.
When you try to run an application like Electron or Google Chrome as the root user without specifying the --no-sandbox flag, the error "Running as root without --no-sandbox is not supported" occurs.
Top Solutions to Fix the Error
To fix the "Running as root without --no-sandbox is not supported" error, follow one of the solutions below.
Solution 1: Adding the --no-sandbox Flag
Adding the --no-sandbox flag when launching the application will resolve the error. However, this solution is not recommended for everyday use, as it disables the security feature and leaves your system vulnerable.
To run Google Chrome with the --no-sandbox flag, open the terminal and execute the following command:
google-chrome --no-sandbox
For Electron, use the following command:
electron --no-sandbox <your-app>
Solution 2: Creating a Non-Root User
A more secure solution is to create a non-root user and run the application under that user account. Follow these steps to create a new user and grant the necessary privileges:
- Open the terminal and execute the following command to create a new user:
sudo adduser <username>
Replace <username> with your desired username.
- Add the new user to the
sudogroup to grant administrative privileges:
sudo usermod -aG sudo <username>
- Switch to the new user account:
su - <username>
- Now, run the application without the
--no-sandboxflag:
google-chrome
Solution 3: Changing Ownership of Application Files
Changing the ownership of the application files to a non-root user can also resolve the error. To do this, follow the steps below:
- Find the location of the application's executable file. For Google Chrome, you can use the following command:
which google-chrome
- Change the ownership of the application files to a non-root user by executing the following command:
sudo chown -R <username> <application-location>
Replace <username> with the non-root user's username and <application-location> with the path to the application's executable file.
- Run the application as the non-root user.
FAQs
Q1: What is a sandbox in application security?
A sandbox is a security feature that isolates an application from the rest of the system to prevent potential security breaches. It restricts the application's access to system resources and limits the potential damage it can cause if compromised.
Q2: Why should I not run applications as the root user?
Running applications as the root user grants them unrestricted access to your system, which poses a significant security risk. If the application is compromised, an attacker can gain complete control over your system.
Q3: Can I use the --no-sandbox flag for all applications?
No, the --no-sandbox flag is specific to applications that use a sandbox for security purposes, such as Electron and Google Chrome. Using this flag for other applications may not have any effect or could cause errors.
Q4: What are the risks of using the --no-sandbox flag?
Using the --no-sandbox flag disables the sandbox security feature, leaving your system vulnerable to potential security breaches. It is not recommended for everyday use, especially when browsing the internet or running untrusted applications.
Q5: Can I switch between multiple user accounts on Linux?
Yes, you can switch between multiple user accounts on Linux using the su command followed by the desired username. For example:
su - <username>
Replace <username> with the account you want to switch to.
