Your Dockerfile doesn't work due to lack of ubuntu version.

• [x ] Ensure the bug was not already reported by searching on GitHub
  under Issues.
• [ x] Be sure to include a title and clear description, as much
  relevant information as possible including:
  • [x ] dReal version (output of dReal --version)
  • [ x] smt2 or drh files with the expected behavior that is not
    occurring (i.e. delta-sat / unsat).
  • [ x] Environment including OS and Compiler (for example, OS X
    10.11.4 + clang-3.6.2)

Literally none of the above things matter here (dReal version, environment, etc.)

here is the issue. In your Dockerfile, you have:

FROM ubuntu

but the latest Ubuntu fails on the line

RUN apt-get -y install -qq autoconf automake bison flex git libtool make pkg-config python-software-properties texinfo

with the output

(base) max@max-XPS-13-9310:~/tools/dreal3/dreal3/dockerbuild$ sudo docker build .

for details see here. But more usefully, you can just fix the issue by specifying the desired Ubuntu version, e.g.:

FROM ubuntu:12.04

Your checklist for a PR is kind of tedious so I won't do it, but the issue ^ above makes it obvious how to fix this, so if you find this useful you can easily implement the fix. Thank you for making this interesting tool which I enjoy learning about and using.
