Unable to find "Arduino IDE" when option "arduino-cli" is set to true under Linux

[legerch]

Hello, I have an issue under Ubuntu 20.04 when setting "Use Arduino Cli" (I am using this option under Win10 also and this work properly).

First, my settings.json :

"arduino.useArduinoCli": true,
"arduino.path": "/snap/bin/arduino-cli",
"arduino.additionalUrls": ""

arduino-cli was installed using snap store (https://snapcraft.io/arduino-cli)

Usage of arduino-cli is set to true, the path is also valid but when I try using arduino extension, I get error message "Cannot find Arduino IDE. Please specify the 'arduino.path'".
Why extension search for Arduino IDE ? Did I miss something ?
I search for similar isssue (#950) but solution are for Windows OS.

Thank you for your time

EDIT :
This pull request seems to fix the problem : #1297

I have the same problem @legerborea , were you able to fix it or do something ?

Hello @Galex1223, no I try to set the commandPath to arduino-cli (instead of arduino default value). But I ended up with an other error :

[Starting] Update package index files...
dummy
Error initializing instance: Error downloading library_index.json.gz: Get "https://downloads.arduino.cc/libraries/library_index.json.gz": dial tcp: lookup downloads.arduino.cc on [::1]:53: dial udp [::1]:53: socket: permission denied
Invalid argument passed: invalid item dummy
[Error] Exit with code=7

So I am not sure that setting commandPath value is enough...

try this

"arduino.useArduinoCli": true,
"arduino.path": "/snap/bin/",
"arduino.commandPath":"arduino-cli",
"arduino.additionalUrls": ""

I am experiencing the same issue. I have tried both settings.json configurations suggested by @legerborea and @pruge. In both cases I receive the error message "Cannot find Arduino IDE. Please specify the 'arduino.path'".

I have confirmed the instillation of arduino-cli is working and I am pointing to the correct fie.

[Galex1223]

try this

"arduino.useArduinoCli": true,
"arduino.path": "/snap/bin/",
"arduino.commandPath":"arduino-cli",
"arduino.additionalUrls": ""

Hey @pruge. sorry for the delay! My arduino-cli installation is not located in /snap/bin, but I pointed to it correctly using the same other setting as you and still has the error messagge refered by @nick-pestell !

Thank you for your update.

1. install arduino-cli
   This script will install the latest version of Arduino CLI to $PWD/bin:

curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh

2. check arduino version
   If you are using a Mac

/Users/<user id>/bin/arduino-cli version

arduino-cli  Version: 0.20.2 Commit: 13783819 Date: 2021-12-09T13:32:05Z

3. vscode arduino options

  "arduino.path": "/Users/<user id>/bin/",
  "arduino.commandPath": "arduino-cli",
  "arduino.useArduinoCli": true,
  "arduino.defaultBaudRate": 9600,

I was able to get the normal snap arduino working with these paths: #1163

Maybe similar paths work for arduino-cli.

[nick-pestell]

Thank you @pruge, I seem to have it working now.

I added #1562 to document this. @legerborea : I guess we can close the issue, right?

[legerch]

Hello @kopp,
Thank you for the review. Unfortunately, I have never succeeded to use this extension with arduino-cli from snap.

I solved message error: "Cannot find Arduino IDE. Please specify the 'arduino.path" with those parameters in extension parameters:

"arduino.useArduinoCli": true,
"arduino.path": "/snap/bin/",
"arduino.commandPath": "arduino-cli"

But then, I am unable to list boards or upload sketches... So I have dropped snap version of arduino-cli and use official binary instead, which perfectly works with this extension.

Long story short, issue can be closed 😉
