Hi @0ohmdash,
Looking through your error logs I can see that you don’t have docker installed.
ERROR: The following required tools (as specified by HOSTTOOLS) appear to be unavailable in PATH, please install them in order to proceed:
docker
You need to apt-get install docker.io.
After installing docker, your user needs to be added to the docker group.
If you want to build only for the imx6ul-var-dart machine you can do:
./balena-yocto-scripts/build/barys -m imx6ul-var-dart
