Hi, I am using snapcraft 7.3.1 revision 8931 to build a gadget snap on a focal vagrant environment, and here is the snapcraft.yaml """ name: test-gadget base: core22 version: 22-0.1 summary: test description: | test only type: gadget architectures: - build-on: amd64 build-for: arm64 confinement: strict grade: stable package-repositories: - type: apt architectures: [ arm64 ] components: [ main ] suites: [ jammy, jammy-security, jammy-updates, jammy-backports ] key-id: F6ECB3762474EDA9D21B7022871920D1991BC93C url: http://ports.ubuntu.com/ubuntu-ports parts: prepare-device-deps: plugin: nil stage-packages: - bsdmainutils:arm64 stage: - usr/bin/hexdump """ After the snap is built successfully, it turns out that the bsdmainutils downloaded is actually from amd64 instead of arm64. I have done some investigation and come up with two potential solution 1. the python-apt somehow return a amd64 package name in "get_providing_packages()" in "python-apt/apt/cache.py", so maybe we can try to check the arch before return the list. However, the "mark_packages()" in "craft_parts/packages/apt_cache.py" will also need to check the length of returned list first instead of accessing the first element directly 2. maybe check the arch in the "mark_packages()" in "craft_parts/packages/apt_cache.py" Please let me know if you need any further info from me, any suggestions for how to fix is very welcome, and I am happy to try to provide fix with PR as well if there is a plan on how to fix
