Error detecting boards

[evanmoring]

Bug Report

Current behavior

The command arduino-cli board list

Returns this:

Error detecting boards: Error getting board list: [listing ports from discovery builtin:serial-discovery: command failed: Error while enumerating serial ports: open /sys/devices/pci0000:00/0000:00:14.0/usb1/1-2/idVendor: permission denied]

I get the same error when I try to upload compiled code.

I checked the permissions on idVendor and they seem fine: -r--r--r-- 1 root root,

I can detect and upload sketches to the board from the arduino ide.

Expected behavior

I expected it to detect my board

Environment

arduino-cli alpha Version: 0.19.3 Commit: 12f1afc Date: 2021-10-12T10:15:19Z

• OS and platform:

The board is an Arduino Uno R3, same thing happended with an UNO SMD R2

Additional context

Hi @evanmoring. Thanks for your report. We don't provide support specific to the Snap installation of Arduino CLI. Please try latest nightly official build of Arduino CLI and then comment here to let us know whether the same problem still occurs.

Download links are here:
https://arduino.github.io/arduino-cli/latest/installation/#nightly-builds

The nightly build won't affect your Snap installation at all, so you are welcome to continue to use the Snap installed version of Arduino CLI for your regular usage.

Thanks for the quick response, I will give that a try. Best, Evan

There is a report of a similar error, this time using the official Arduino CLI:
https://forum.arduino.cc/t/arduino-cli-error-getting-board-list/925367

$ arduino-cli board list
Error detecting boards: Error getting board list: [listing ports from discovery builtin:serial-discovery: command failed: Error while enumerating serial ports: open /sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.1/idVendor: permission denied]

I'm have the same issure. Using ardiono-cli in Ubuntu 20.04.3. I get the same error when I ry to arduino-cli board list.

[karthikeyan-krish]

Fixed. Try adding tty and dialout group to your user.
->sudo usermod -a -G tty $USER
->sudo usermod -a -G dialout $USER
Now I can see my board.

@karthikeyan-krish's solution did not fix it for me :-(

$ arduino-cli board list
Error detecting boards: Error getting board list: [listing ports from discovery builtin:serial-discovery: command failed: Error while enumerating serial ports: open /sys/devices/pci0000:00/0000:00:08.1/0000:07:00.3/usb4/4-2/idVendor: permission denied]

Calling arduino-cli with sudo doesn't help either.

I have installed arduino-cli via snap on Ubuntu 21.04.

@frederikheld can you try using an arduino-cli installed without snap?
We need to understand if it's an issue with the snap package or a bug in the code.

Download links to latest version are here: https://arduino.github.io/arduino-cli/0.20/installation/#latest-release

@silvanocerza: I tried with your installation method and it yielded exactly the same error.

Some feedback about your recommended installation method:

• I don't like to pipe scripts downloaded from the public web directly into sh (and I don't think we should encourage anyone to do so)
• I don't like scripts that install binaries into visible directories in my home directory (my home directory is to get work done, not to clutter it with random stuff that just lays around there)
• I don't like scripts that need me to dive into the intricate depths of unix install locations and path declarations if I want to install it somewhere else (it's a mess, we all know it, I assume that's why you chose to go the simple way and just drop it in my home dir)
• I really like automatic updates

That's why I prefer apt and snap ...
