Permission denied (publickey)

I am getting this error while running this project
We have already setup the deploy key in git and CircleCI and we are able to checkout the code.
We are passing two repositories in requirement.txt . while cloning these repository I am getting the following error:

Running command git clone -q 'ssh://’ /opt/venv/src/****
Warning: Permanently added the RSA host key for IP address ‘’ to the list of known hosts. Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Hi @kambley! In the past, I’ve seen similar issues when a key was removed from GitHub. You may need to remove and re-add the deploy key (under Project Settings >> SSH keys

Let me know if that works!
