### Bug Description We have 'amd64' hardcoded in some of the package service integration tests that cause them to fail on other architectures. ### To Reproduce https://github.com/canonical/charmcraft/actions/runs/12205703353/job/34053604513?pr=2015 ### Environment Canonical hosted GH CI, arm64 ### charmcraft.yaml ```yaml n/a ``` ### Relevant log output ```shell =========================== short test summary info ============================ FAILED tests/integration/commands/test_pack.py::test_build_basic_charm[platforms-jammy-charm] - IndexError: list index out of range FAILED tests/integration/services/test_package.py::test_write_metadata[complex-legacy] - RuntimeError: Could not determine run-on bases.
