Building custom Yocto-Linux image fails

Hello,

I would like to ask if anyone was successful in building a custom Yocto-Linux image for the Portenta X8 according to the Manual provided by Arduino Team https://docs.arduino.cc/tutorials/portenta-x8/image-building/

The docker build is failing with a message that libc6-dev-i386 could not be found. However, I was able to overcome this message by removing the i386. Unfortunately the docker build process fails again during the build of ostreeuploader using Go.

I tried two systems for this:
(1) Mac OSX with Apple Silicon M3
(2) Virtualized Ubuntu (VMWare Fusion) running on the Apple Silicon M3

On both systems the build process fails.

Before digging into more details, I would like to know if anyone was successful with building a custom image for the Portenta X8.

Any help is appreciated!

Kind regards,

Can anyone share experiences?
