Are you sure that is the full error message? It doesn’t really describe what went wrong exactly. It says there is an error, but it doesn’t say what the error was specifically.
As I said previously I built the sample container image from scratch, so I’m fairly confident it does build successfully.
If I were to take a guess at what your issue might be. I assume you’re building this on your development PC, correct? If that is the case did you make sure to enable arm emulation, so that arm/arm64 based-containers can be built on a non-arm machine?
Details about enabling arm emulation can be found here: Configure Build Environment for Torizon Containers | Toradex Developer Center
