### Bug Description When packing or building a rock that has an `arch` different than the host machine, the execution will be just interrupted w/o any helpful message. ### To Reproduce 1. Create a `rockcraft` project with arch `amd64` 2. Run `rockcraft pack -v` on a machine with `arm64` 3. Observe the only output: ``` $ rockcraft build -v Starting rockcraft, version 1.5.3 Logging execution to '/home/ubuntu/.local/state/rockcraft/log/rockcraft-20240910-201153.008216.log' ``` ### Environment 1. `arm64` machine 2. `rockcraft` 1.5.3 3. Ubuntu 22.04 ### rockcraft.yaml ```yaml https://github.com/canonical/kubeflow-rocks/blob/main/admission-webhook/rockcraft.yaml ``` ### Relevant log output ```shell $ vim /home/ubuntu/.local/state/rockcraft/log/rockcraft-20240910-202338.827485.log 2024-09-10 20:23:38.828 Starting rockcraft, version 1.5.3 2024-09-10 20:23:38.828 Log verbosity level set to BRIEF 2024-09-10 20:23:38.828 Configuring application... 2024-09-10 20:23:38.828 Preparing application... 2024-09-10 20:23:38.829 Build plan: platform=None, build_for=None 2024-09-10 20:23:38.829 Loading project file '/home/ubuntu/kubeflow-rocks/admission-webhook/rockcraft.yaml' 2024-09-10 20:23:38.831 Processing grammar (on arm64 for arm64) 2024-09-10 20:23:38.831 Processing grammar for plugin: nil 2024-09-10 20:23:38.831 Processing grammar for override-build: mkdir -p ${CRAFT_PART_INSTALL}/usr/share/rocks (echo "# os-release" && cat /etc/os-release && echo "# dpkg-query" && dpkg-query -f '${db:Status-Abbrev},${binary:Package},${Version},${source:Package},${Source:Version}\n' -W) > ${CRAFT_PART_INSTALL}/usr/share/rocks/dpkg.query 2024-09-10 20:23:38.831 Processing grammar for plugin: go 2024-09-10 20:23:38.831 Processing grammar for build-snaps: ['go/1.21/stable'] 2024-09-10 20:23:38.831 Processing grammar for source: https://github.com/kubeflow/kubeflow.git 2024-09-10 20:23:38.831 Processing grammar for source-tag: v1.9.0 2024-09-10 20:23:38.831 Processing grammar for source-depth: 1 2024-09-10 20:23:38.831 Processing grammar for source-subdir: components/admission-webhook 2024-09-10 20:23:38.831 Processing grammar for organize: {'webhook': '/webhook'} 2024-09-10 20:23:38.831 Processing grammar for plugin: nil 2024-09-10 20:23:38.831 Processing grammar for after: ['admission-webhook'] 2024-09-10 20:23:38.831 Processing grammar for overlay-script: # Create a user in the /home/ubuntu/kubeflow-rocks/admission-webhook/overlay/overlay chroot groupadd -R /home/ubuntu/kubeflow-rocks/admission-webhook/overlay/overlay -g 1001 ubuntu useradd -R /home/ubuntu/kubeflow-rocks/admission-webhook/overlay/overlay -M -r -u 1001 -g ubuntu ubuntu 2024-09-10 20:23:38.831 Processing grammar for override-prime: craftctl default 2024-09-10 20:23:38.831 Processing grammar for plugin: nil 2024-09-10 20:23:38.831 Processing grammar for stage-snaps: ['pebble/latest/stable'] 2024-09-10 20:23:38.831 Processing grammar for override-prime: craftctl default mkdir -p var/lib/pebble/default/layers chmod 777 var/lib/pebble/default 2024-09-10 20:23:38.831 Processing grammar for stage: ['bin/pebble'] ```
