How to access a device with Arduino IDE Flatpak

  • 772

I've installed Arduino IDE (1.8.5) with Flatpak (Kubuntu 18.04).

Attached my Wemos D1 Mini to the USB port, but can't upload a sketch:

An error occurred while uploading the sketch
error: cannot access /dev/ttyUSB0

Seems a bit silly that an IDE for a device in Flatpak can't access a device out of the box.

How do I fix that?

This question is about Flatpak.

What additional action is necessary to get the Flatpak version of Arduino IDE working with a device?

(IMHO Flatpak needs to provide additional info/help in some way, installing with Ubuntu Make umake seems easier.)

  1. The problem is that the app starts with flatpak and that by default blocks devices. See Accessing Serial Ports with an Application Runs in Flatpak by adding --device=all you get it work, but see comments on link.

    Most likely that's because Flatpak is blocking access to the serial device.

    Unfortunately at the moment I don't think there is a way to give access specifically to the serial devices, so you'd need to give access to all:

    flatpak run --device=all com.xamarin.MonoDevelop

    What this does is essentially mount the host's /dev inside the sandbox, so the app has full access to it.
