Unable issue certificate

Hi All,

I am running cert-issuer on docker. I followed steps which are provided in github GitHub - blockchain-certificates/cert-issuer: Issues Blockcerts using either the Bitcoin or Ethereum blockchain.
I am unable issue certificate, because am getting following error when I run " cert-issuer -c /etc/cert-issuer/conf.ini" command.

bash-4.3# cert-issuer -c /etc/cert-issuer/conf.ini
Traceback (most recent call last):

Hi,
This looks like an old version of the code – we haven’t had a file named main.py for a while. This can happen if there are old docker images left around. I run this to clear out old images and containers:

#!/bin/bash

docker rm -v $(docker ps -a -q -f status=exited)

docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker:/var/lib/docker --rm martin/docker-cleanup-volumes
