Hello. I am working through the Torizon Quickstart. I am on the last chapter of Module 2, “Build and Run Your First Python Application”, Step 9.
After pressing F5, here’s the output I have:

Backend local instance running on port 5000
No active configuration found, selecting first valid one.
Active configuration has been selected (817aab27-0771-474b-b9e5-18b18a02e08d), updating it.

Local docker exception.

I followed all of Docker’s instructions when installing it, including adding myself to the ‘docker’ group and rebooting.
VS Code sees my SOM and the containers running on it.
The only issue I can think of…
The SOM has Docker version:

apalis-imx8-06543194:~$ docker --version
Docker version 19.03.12-ce, build 48a66213fe

And my Ubuntu has Docker version:

$ docker --version
Docker version 19.03.13, build 4484c46d9d

Greetings @cb_cross,

I’m unable to recreate this error on my side. Judging by the error message you pasted though, one possible issue is that arm emulation isn’t properly enabled. Have you ran this command on your development machine, as stated on the previous page of the quickstart: Install the Build Environment for Torizon

Alternatively you could also execute the following command in Visual Studio Code via the command prompt: “Torizon: Enable ARM emulation for Docker containers”. Though this should do the same thing as the command above.

To confirm that the arm emulation was successfully enabled on your development machine try running this command on your development PC: docker run --rm -it arm64v8/debian arch. If successful this should return aarch64.

Best Regards,
Jeremias

All I can do is chuckle and shake my head.
I did run docker run --rm -it --privileged torizon/binfmt previously. But running it again seems to have solved the issue. I have completed the exercise.
Thank you.

Glad you were able to resolve this!
