I was able to build swarmkit on arm64 after I manually installed a newer golang-github-docker-docker-dev.
There's some kind of circular dependency between swarmkit and docker.io. I think someone will have to break it with a binary upload. (There was a binary upload on amd64, I notice.) According to my "history", I did something like: apt-get build-dep docker.io apt-get build-dep swarmkit apt-get install golang-github-docker-docker-dev wget http://ftp.uk.debian.org/debian/pool/main/d/docker.io/golang-github-docker-docker-dev_1.13.1~ds2-3_all.deb dpkg -i golang-github-docker-docker-dev_1.13.1~ds2-3_all.deb apt-get install golang-github-opencontainers-docker-runc-dev apt --fix-broken install dpkg -i golang-github-docker-docker-dev_1.13.1~ds2-3_all.deb apt-get source swarmkit cd swarmkit-1.12.0+git20170111.763.296fcfcf dpkg-buildpackage -b
