Neutrinos Studio is not opening or working on my Ubuntu system

dhishon · February 26, 2025, 5:31am

I had installed the desktop app , but when i try to open it is not opening. i had tried many times but not working.

Could you please provide more information about the issue? Are you seeing any specific error messages on the screen when you try to open the app?

dhishon · February 26, 2025, 10:16am

There is no specific error message. I am using Ubuntu, and when I double-click on Neutrinos Studio, nothing opens. When I click multiple times (show only sometimes), Ubuntu displays a “Not Responding” message and prompts me to send a report.

Could you please specify:

Your Ubuntu version.
Your Node.js version

Additionally, I recommend deleting the .neutrinos folder under your home directory. Keep in mind that this folder is hidden by default, so you might need to enable hidden files to see it

Ubuntu VERSION="24.04.2 LTS
Node Version v20.18.0
Also i had deleted the .neutrinos folder .

@ragesh-a please help

It looks like your desktop app is being blocked due to security restrictions in Ubuntu 24.04, likely caused by user namespace restrictions or AppArmor policies.

Temporary Fix

Run the following command in the terminal:

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

Then, launch the app using:

n-studio

Alternative Solution

If the issue persists, consider downgrading to Ubuntu 22.04, where the app works without issues.

Okay, I ran the above commands, and at that time, it showed an NVM error stating that I needed to downgrade to version 10 or below. I did that, and it opened, but only in the terminal. So, I have to run n-studio manually every time. When I try to open it using the GUI, it doesn’t work and still shows the NVM error.

Additionally, when I run it in the terminal, it displays the following output

Based on the logs I provided, it seems to work manually via the terminal, but the GUI method is not functioning

what NVM error are you getting?

You’ll need to run the following command to set the default version for node on the system so that the application can start.

nvm alias default 20

@arane please have a look at this

dhishon · March 3, 2025, 2:35pm

I had tried .. but same issue.

Eldho · March 4, 2025, 6:04am

@ragesh-a please take look and provide the assistance

ragesh-a · March 4, 2025, 6:17am

Ensure that you are using Node version 20. If you have installed Node using NVM (Node Version Manager), make sure that the Node version persists across all terminal tabs.
