### Bug Description When building on launchpad via remote-build a core20 snap for armhf, the traceback in this output is printed. This happens deterministically in our daily builds that are dispatched via snapcraft 7. ### To Reproduce I think this should happen building any core20 snap via remote-build (as there is nothing special in what we do and if fails to run as soon as it is picked up for any core20 armhf snap we build) ```shell git clone https://github.com/canonical/checkbox cd checkbox/checkbox-snap ./prepare.sh series_classic20 snap refresh snapcraft --channel=7 snapcraft remote-build --build-for=armhf ``` ### Environment Workflow: https://github.com/canonical/checkbox/blob/main/.github/workflows/checkbox-snap-daily-builds.yml ### snapcraft.yaml ```yaml name: checkbox summary: Checkbox test runner description: | Checkbox is a flexible test automation software.
