CircleCI builds failing - invalid/missing SSH key

[mmrwoods]

@rhyeal Looks like the SSH key stored on CircleCI is no longer valid, which is preventing builds from completing (they don't even get past checking out the code)...

Using SSH Config Dir '/home/circleci/.ssh'
git version 2.17.1
Cloning git repository
Cloning into '.'...
Warning: Permanently added the ECDSA host key for IP address '140.82.112.4' to the list of known hosts.
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

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

Closing as no longer relevant, build process abandoned for now, if restored, should be simplified
