It seems like the first one isn't working because your user doesn't have the permissions for changing that directory, and the second because your root user doesn't have the right SSH keys for accessing that git repository.
Depending on what you're trying to do, it might be better to clone the repository to a different directory, or maybe
chown the current directory to have full access for your user
