One of those djissis duh moments - trying to check out a public git repo, but failing due to authentication …
git clone firstname.lastname@example.org:cobusbernard/Scripts.git Cloning into 'Scripts'... Warning: Permanently added the RSA host key for IP address '188.8.131.52' 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.
So I checked my ssh setup / keys, but nothing in there looks dodgy:
ls ~/ssh/ known_hosts
So it ended up being ssh vs https cloning. SSH checkout is always authenticated.
