[Bug]: ansible feature failes with Exec format error (Missing shebang)

[morgan-lindqvist]

Feature id and version

ghcr.io/devcontainers-extra/features/ansible:2

Dev Container base Image

mcr.microsoft.com/devcontainers/base:trixie

What happened?

When building a multi architechture (linux/amd64, linux/arm64/v8) devcontainer (devcontainer.json se below) on linux/amd64 the build fails when adding the ansible feature with the error message below.

Building a single architechture build for amd64 on amd64 works fine

Looking at the install.sh for the ansible featue the shebang is missing (https://github.com/devcontainers-extra/features/blob/main/src/ansible/install.sh)

The guidelines for writing a feature (https://containers.dev/guide/author-a-feature) clearly shows that there should be a sheband in first line.

If I fork the repository and add a shebang on the first line and them deploys the feature locally the devcontainer builds without any issues.

The shebang was removed for the ansible feature as well as for a number of other features i this commit: 756258d

The devcontaainer.json looks as follows (written from memory so there might be a typo but I do not think so)
{ "image": "mcr.microsoft.com/devcontainers/base:trixie", "features": { "ghcr.io/devcontainers-extra/features/ansible:2": {} } }

Proposal: Add the shebang back for all the features it was removed from or make sure install.sh can be executed without it.

Relevant log output

Error while loading /tmp/dev-container-feature/ansible_0/./install.sh: Exec format error

@danielbraun89 , your commit (756258d) a while back introduzed a bug when building a multiarchitectur devcontainer.

Do you know why?

Why did you remove the shebangs, the commit is not clear.

Thanks beforehand for any help trying to solve this issue.
