Ubuntu Installation Fail

[christroutner]

Brief Description:
I tried installing the master branch branch on my Ubuntu box. Both the Docker container and the build according to these ubuntu instructions failed in the same way. Details below.

Operating System (OS and version): 16.04
OpenBazaar version: OpenBazaar-Server master branch at b5e6d38
Hardware: VirtualBox on Windows 10 running Ubuntu VM

Reproducible (Always / Almost Always / Sometimes / Rarely / Couldn't Reproduce): Always

Steps to reproduce:

1. Running the Docker image with Compose generated the following errors:

...
************* Module market.contracts
market/contracts.py:1477: [I:locally-disabled] -- Locally disabling unused-variable (W0612)
market/contracts.py:1478: [I:locally-disabled] -- Locally disabling cell-var-from-loop (W0640)
************* Module market.migration
market/migration.py: 93: [C:line-too-long] -- Line too long (141/116)
market/migration.py:131: [C:line-too-long] -- Line too long (119/116)
market/migration.py:  8: [W:unused-import] -- Unused import requests
************* Module market.transactions
market/transactions.py:174: [I:locally-disabled] -- Locally disabling cell-var-from-loop (W0640)
************* Module market.network
market/network.py:850: [I:locally-disabled] -- Locally disabling unused-variable (W0612)
make: *** [pycheck] Error 1
FAIL: Detected 3 files with errors.
Makefile:14: recipe for target 'pycheck' failed
ERROR: Service 'openbazaard' failed to build: The command '/bin/sh -c make' returned a non-zero code: 2

2. Running the instructions for installing on Ubuntu generated nearly the same error messages. Below is the tail end of running make, and then trying to run the Bazaar server:

...

Update:

I was able to get the server to run on Ubuntu using the fix in this issue

this is fixed by changing pyopenssl==16.0.0 to pyopenssl==16.2.0 in requirements.txt
