IDE hangs on startup: "mkdir /Users/papahotel: permission denied"

Development Tools IDE 2.x
1

Hi,

I have tried downloading IDE 2.0 to my Mac Studio running MacOS Monterey, but it only gets to a black app background with the new Arduino logo.

I used terminal to run the command:

"/Applications/Arduino IDE.app/Contents/MacOS/Arduino IDE" with the following printout. I hope this helps sort out any issues. I have no problems with IDE 1.8.19.

Hi @mysterons

Do you have any idea why your operating system would deny the Arduino IDE permission to create this folder?

3

There isnt a user called papahotel (anymore) deleted a few years ago. Perhaps a relic from when I copied over the backup from the old imac to the new machine?

4

Found the problem - just had to run the command as superuser:

sudo "/Applications/Arduino IDE.app/Contents/MacOS/Arduino IDE"

All running ok now.

5

Thanks for taking the time to post an update with your findings @mysterons. I'm glad you got it working now.

It should not be necessary to run Arduino IDE as superuser, but it seems there is a problem with your system configuration.

6

I am having a real problem trying to run IDE 2.0 on a new Mac Studio with a clean install of Monterey. I have one user set up on the mac but the IDE is trying to install to an old (now deleted user) 'papahotel' Is there a way to for the installer to use the current user. I have deleted Arduino15, removed the Arduino folders and still the same. Why is it picking up an old user rather than the current one? I have no problems with IDE 1.18.

The error message displayed:

Error saving downloaded index: open
/users/papahotel/Library/Arduino15/package_index.json: permission denied

Thanks in advance.

Hi @mysterons. I'm sorry to hear you are still having trouble with this bad system configuration.

In order to gather more information that might help us to troubleshoot your problem, I'm going to ask you to run a command from the command line terminal, then share the output.

Please do this:

  1. Open your Applications folder.
  2. Open Utilities.
  3. Double-click on "Terminal".
  4. Type the following command:
    echo "$HOME"
  5. Press Enter
  6. Press ⌘+A.
    This will select all the text in the terminal window.
  7. Press ⌘+C.
    This will copy the selected text to the clipboard.
  8. Open a forum reply here by clicking the Reply button.
  9. Press ⌘+V.
    This will paste the output into the code block.
  10. Click the Reply button to post the output.

Please let me know if you have any questions or problems while following those instructions.

Hi,

Thanks for your time on this.

This is the screen grab:

Last login: Thu Oct 6 07:59:44 on console
Pete@Petes-Mac-Studio ~ % echo "$HOME"
/Users/Pete
Pete@Petes-Mac-Studio ~ %

9

The default configuration will base the location on the path defined by the HOME environment variable, so It should use the correct /Users/Pete/Library/Arduino15 instead of /Users/papahotel/Library/Arduino15.

I think the problem might be that the configuration file where this path is stored was was created at a time when the HOME variable still had the previous username. In this case, the solution will be to delete the configuration file, which will cause the Arduino IDE to create it over again with the right user name. I'll provide instructions:

  1. Close the Arduino IDE window if it is running.
  2. Delete the file at this path:
    /Users/Pete/.arduinoIDE/arduino-cli.yaml
    • :warning: Please be very careful when deleting things from your computer. When in doubt, back up!
    • :exclamation: The /Users/Pete/.arduinoIDE folder might be hidden by default in Finder. You can use the Command+Shift+. keyboard shortcut to reveal it.

Now try starting the IDE again. Hopefully it will start up without any problems this time.

Please let me know if you have any questions or problems while following those instructions.

Hi,

This seems to have sorted things out for me. The IDE now works everytime!

Thank you for taking the time to help resolver this - very much appreciated.

You are welcome. I'm glad it is working now.

Hi @ptillisch I'm having the same problem as mysterons: I'm trying to download and run arduino 2.0.3 on my mac running Monterey 12.5 but when I open the application, no window appears, even though arduino opens in the menu bar. I went into terminal and tried to open it from the backend using ""/Applications/Arduino IDE.app/Contents/MacOS/Arduino IDE"" but this is the reply I get.

I've never had a user called eleanormayes%201, so I'm not sure where it is getting that from. I also removed my old sketchbook from my documents (I put it on an external drive) and deleted it from my computer, as well as removing the Arduino15 folder before I tried installing 2.0.3 again. No luck unfortunately. Any help or other ideas you can provide would be amazing, thank you!

Hi @emayes

Have you made any modifications, or is there anything notable about your "hosts file", especially in regards to the definition of localhost?

The "hosts file" is located at /etc/hosts (AKA /private/etc/hosts).

%20 is "percent encoding" for the space character in your username eleanormayes 1. This is not related to the problem.

14

That was it! Turns out my hosts file was corrupted, and when I repaired it the IDE opened properly! Thanks so much

15

You are welcome. I'm glad it is working now. Thanks for taking the time to post an update with your solution!

Per
