Error when trying to run docker-compose up. "oci runtime error: container_linux.go:247..." #4039

ERROR: for app  Cannot start service app: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"script/docker-entrypoint.sh\\\": stat script/docker-entrypoint.sh: no such file or directory\"\n"
ERROR: compose.cli.main.main: Encountered errors while bringing up the project.
I've tried reinstalling docker, docker-compose, virtualbox, rebuilding containers, recreating machines.

Downgrading almost all of those things to previous versions. Literally retrying the whole docker instalation flow.
The problem occurs only in docker-compose up. Everything works fine when I use docker run ....

The important thing is the whole setup works correctly on my OSX installation. Unfortunately my Xenial Ubuntu doesn't want to cooperate.
I've checked the issues archive and couldn't find an answer that would help me fix the problem.
Here are my whole setup configs:

docker-compose.yml:
version: "2"
services:
    build: .
    volumes:
      - .:/app
    depends_on:
      - cache-redis
    links:
      - cache-redis
  nginx:
    image: nginx:1.11.1-alpine
    depends_on:
      - app
    links:
      - app
    ports:
      - "80:80"
    volumes:
      - ./config/nginx/app.conf:/etc/nginx/conf.d/default.conf
  cache-redis:
    image: redis:3.2.1-alpine
    volumes:
      - cache-redis:/var/lib/cache-redis/data
volumes:
  cache-redis:
    driver: local
