Rest Api failed to build

[Enthusiast-block]

Hi, I am trying to run the sample application in my system. I am following the edx course and after I have cloned the repo.

I do a docker-compose up, and the this issue comes up :-

E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-libc-dev_4.15.0-139.143_amd64.deb 404 Not Found [IP: 91.189.88.142 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? ERROR: Service 'simple-supply-rest-api' failed to build : The command '/bin/sh -c apt-get install -y --allow-unauthenticated -q python3-grpcio-tools python3-pip python3-sawtooth-rest-api python3-sawtooth-sdk' returned a non-zero code: 100

Can anyone explains why this comes and how can it be resolved?

if you are still looking for a solution, one guy in the previous issues wrote: " This is due to version mismatch. Go to /shell/Dockerfile at line 39 change grpcio-tools \ with grpcio-tools==1.29.0 . This will solve your issue. You can check out my updated version of sawtooth-marketplace. "
