Do not key in messages, do screen grabs. You will also need to show directories with attributes etc to ensure it is executable.  
Remember we can NOT see what you see, so do screen grabs of what you see.

Hi @fatter. Try downloading a fresh copy of the AppImage. It is available from the Software page here:

[https://www.arduino.cc/en/software#ide-download-section](https://www.arduino.cc/en/software#ide-download-section)

It is possible that your local file was somehow corrupted.

downloaded it. set to runnable status. dont started. i tried to command line too:  
error message is: not exist this direktory or file. i read other pages the need to install fuse but it installed before:  
fuse3/noble,now 3.14.0-5build1 amd64 [telepítve, automatikus]

i used the command : sudo usermod -a -G dialout with my own name too  
could you give me any other ideas. i dont wish reinstall the ubuntu again 🙂

remember that i working esp32 and i wish contact to Lora modul. the lora modul have settings for parameters a (modem this not sure) esp32 dev use cp2101 serial and the Lora modul modem use ch340.  
Could this situation be causing the problem?

Please don't paraphrase error messages when sharing them on the forum. Copy the exact text of the message and paste it to your forum post.

Please do this:

1. Attempt to start the AppImage package from the command line, exactly as you did before when you encountered that error message.
2. Use the mouse to select all the text in the terminal window.
3. Press the **Ctrl** + **Shift** + **C** keyboard shortcut.  
This will [copy](https://lifehacker.com/how-to-copy-cut-and-paste-for-beginners-5801525) the selected text to the clipboard.
4. Open a reply here on this forum topic by clicking the " **Reply**" button.
5. Click the **`<CODE/>`** icon on the post composer toolbar.  
This will add the forum's code block markup ( **`````** ) to your reply to make sure the error messages are correctly formatted.

today start the system I attempt to start the AppImage file from command line. i get the next error message:

The problem is the first `.` here:

> [@fatter](#):
>
> $ . ./arduino-ide\_2.3.8\_Linux\_64bit.AppImage

This causes the contents of the file that is passed as an argument to be executed in the shell:

[https://www.gnu.org/software/bash/manual/bash.html#index-\_002e](https://www.gnu.org/software/bash/manual/bash.html#index-_002e)

(similar to running an executable shell script file)

You should not use this to execute a binary file like the AppImage package.

So remove the first `.` from the command and try again:

```plaintext
./arduino-ide_2.3.8_Linux_64bit.AppImage

```

hi,  
i have got advise to fix this problem.

1,download the zip of arduino ide  
2, upzip it  
3, set to owner the root of the chrome-sandbox file

4, set to mode this 4755 and working right the Arduino Ide  
thank you very much!

Thanks for taking the time to post an update @fatter!

This error is caused by the [**AppArmor**](https://apparmor.net/) security software blocking the **Arduino IDE** application from starting.

In that thread, multiple solutions are described by an Arduino community member. In addition to the solution you found, and alternative is described, which is to create an [**AppArmor** policy](https://gitlab.com/apparmor/apparmor/-/wikis/AppArmor_Core_Policy_Reference) for the Arduino IDE application:

[https://github.com/arduino/arduino-ide/issues/2429#:~:text=file)%2C%20you%20can-,create%20an%20AppArmor%20profile,-with%20a%20configuration](https://github.com/arduino/arduino-ide/issues/2429#:~:text=file%29%2C%20you%20can-,create%20an%20AppArmor%20profile,-with%20a%20configuration)

> You can also create a new AppArmor profile for the Arduino IDE (that allows a non-root user to use the sandboxing in a specific application). If you copy the AppImage file to `/usr/local/bin/arduino` (this is the new name of the AppImage file), you can create an AppArmor profile with a configuration file, for example, in `/etc/apparmor.d/usr.local.bin.arduino`, containing:
> 
> ```plaintext
> abi <abi/4.0>,
> include <tunables/global>
> profile arduino /usr/local/bin/arduino flags=(unconfined) {
> userns,
> include if exists <local/arduino>
> }
> 
> ```
> 
> and reloading all AppArmor profiles with:
> 
> ```plaintext
> sudo service apparmor reload
> 
> ```
> 
> Now you can run the Arduino IDE without the sandboxing error.

I have verified that the **AppArmor** policyapproach does fix the problem.

Unfortunately since I am not knowledgeable in this area and the [**AppArmor** documentation](https://gitlab.com/apparmor/apparmor/-/wikis/Documentation) is absolutely horrendous. For this reason, despite my best efforts, I was not able to effectively analyze the policy provided by the community member. So I can't officially endorse the installation of that policy. However, I don't have any reason to believe it is flawed or dangerous, and I am using it on my own Ubuntu 24.04 machine.
