### Bug Description Building a ROCK for arm does not work on a Raspberry Pi 3 running the 32 bit version of Ubuntu 22.04. Rockcraft simply refuses to build with the following error message: ``` Error for platform entry 'arm': this machine's architecture (armv7l) is not compatible with the ROCK's target architecture. Can only build a ROCK for arm if the host is compatible with ['arm']. ``` ### To Reproduce ``` rockcraft init sed -i "s/amd64/arm/" rockcraft.yaml rockcraft --verbose ``` ### Environment Raspberry Pi 3 Model B Ubuntu Server 22.04.2 LTS ### rockcraft.yaml ```shell name: my-rock-name # the name of your ROCK base: ubuntu:22.04 # the base environment for this ROCK version: '0.1' # just for humans.
