I am trying to create a single docker file where cert-tools and cert-issuer coexist.

Recently I made progress with cert-tools . I was able to create a docker image where cert-tools is installed and running.  
Now I am trying to install cert-Issuer as well in this image.  
**Currently I am getting the following error-**  
**ERROR: No matching distribution found for coincurve==7.1.0**

Also I am using Ethereum Blockchain. So I think I need to do below change ,ie mention in the setup file for cert-issuer as

> def initialize\_options(self):  
> self.blockchain = ‘ethereum’ #make ethereum as default chain

Have you tried setting another available version of `coincurve` as the requirement ?  
I am not sure when this code was set, but if you take the minor version just above you should be good.

The issue is fixed by updating the docker file and installing coincurve before chainpoint  
…  
&& pip3 install --upgrade pip setuptools   
&& pip3 install coincurve\>=7.1.0   
…  
&& mkdir -p /cert-issuer/data/unsigned\_certificates   
&& mkdir /cert-issuer/data/blockchain\_certificates   
&& pip3 install chainpoint\>=0.0.2 \

Thanks for your reply.
