I googled for the issue and found this.

It's a known bug in psycopg2 versions prior to 2.2 but the version I have is 2.7.3 (as per requirements/common.txt). Can't figure out the issue.

Solved by

pip install --upgrade psycopg2-binary

@ChetanMadan I think the problem is that Ubuntu 18.04 is not supported by Fabrik. I was able to install it successfully on Ubuntu 16,04

I just finished setting it up the docker way on Ubuntu 18.04! It is working just fine. @nikochiko

@nikochiko , it would be easier to setup using docker/ docker-compose. Might take some time in building the images but once done, it should be a cake walk ..!
