Django build Failing with NO ERRORS

https://travis-ci.com/github/radugaf/Protocol/builds/167702797

Hi there, can anybody tell me why this build is failling? I have double checked every corner of the code and I could not find it. Also Travis doesn’t tell me much…

PS I am using docker.

https://travis-ci.com/github/radugaf/Protocol/builds/167702797#L547

./core/models.py:2:80: E501 line too long (90 > 79 characters)

This looks like an error message to me.
