[Bug]: Protocol buffer on arm64 - Exec format error

What happened?

I work on an arm64 machine and need protoc in my Dev Container. I added it with

"ghcr.io/devcontainers-extra/features/protoc:1": {
    "version": "29.1"
}

This leads to

protoc --version
bash: /usr/local/bin/protoc: cannot execute binary file: Exec format error

When I remove the feature from devcontainer.json and add apt-get install -y protobuf-compiler to my Dev Container Dockerfile instead, protoc is executable.

Relevant log output

bash: /usr/local/bin/protoc: cannot execute binary file: Exec format error

Thanks for the bug report!

At first glance, as the feature uses gh-release feature under the hood, it may be an issue with filtering by nanolayer. I will take a deeper look

In meantime, if the installation via apt-get works for you, you can use apt-get packages feature to install the package:

{
	"name": "Ubuntu",
	"image": "mcr.microsoft.com/devcontainers/base:ubuntu",
	"features": {
		"ghcr.io/devcontainers-extra/features/apt-get-packages:1": {
			"packages": "protobuf-compiler"
		}
	}
}
