Typos happen, and repository names are case-sensitive. If you try to clone
firstname.lastname@example.org:user/repo.git, but the repository is really named
User/Repo you will receive this error.
To avoid this error, when cloning, always copy and paste the clone URL from the repository's page. For more information, see "Cloning a repository."
To update the remote on an existing repository, see "Managing remote repositories".
If you are trying to clone a private repository but do not have permission to view the repository, you will receive this error.
Make sure that you have access to the repository in one of these ways:
- The owner of the repository
- A collaborator on the repository
- A member of a team that has access to the repository (if the repository belongs to an organization)
In rare circumstances, you may not have the proper SSH access to a repository.
You should ensure that the SSH key you are using is attached to your GitHub user account. You can check this by typing the following into the command line:
$ ssh -T email@example.com > Hi username! You've successfully authenticated, but GitHub does not > provide shell access.
If the repository belongs to an organization and you're using an SSH key generated by an OAuth App, OAuth App access may have been restricted by an organization owner. For more information, see "About OAuth App access restrictions."
For more information, see Adding a new SSH key to your GitHub account.
If all else fails, make sure that the repository really exists on GitHub! If you're trying to push to a repository that doesn't exist, you'll get this error.
