Make sure the architecture name is correct. ``` ### Additional context ``` $ dpkg --print-architecture armhf $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04 LTS Release: 22.04 Codename: jammy $ uname -m armv8l ``` Core20-based snaps build correctly on Ubuntu 20.04 in an armhf container on an arm64 host.
