Tried to reduce complexity and executed balena-engine only on a simple Dockerfile which may hint about the issue since this produce “unexpected EOF”.
The output are as follows:
balena-engine build --file Dockerfile .

NOTE: I got a ubuntu 16.04.6, using balena-cli 11.9.3 and balena-engine 17.12.0 which works as expected.
I will try downgrade balena-engine to 17.12.0.
