"docker-compose build" returning "exec format error"

General

When running the “docker-compose build” command, I’m running the following error:

standard_init_linux.go:207: exec user process caused "exec format error"
ERROR: Service 'seafile' failed to build: The command '/bin/sh -c apt-get 
update && DEBIAN_FRONTEND=noninteractive apt-get install -y ca-
certificates python2.7 python-setuptools python-imaging python-ldap 
python-urllib3 sqlite3 wget' returned a non-zero code: 1

My dockerfile looks like:

# FROM armv7/armhf-debian

I’m new to docker/Debian9 so I’d appreciate any help. :slight_smile:
