Git：权限被拒绝（公钥）。 致命：无法从远程存储库读取

Question

I've never cloned a private GitHub repository. So I followed GitHub's guide but it's still rejecting me. I have a Red Hat linux server on AWS. I did the following:

1. Ran ssh-keygen -t rsa -b 4096 -C "< my github email address >" .
2. Ran eval "$(ssh-agent -s)" .
3. Ran ssh-add ~/.ssh/id_rsa .
4. Ran cat ~/.ssh/id_rsa.pub (to get the value of the key).
5. Added output of step 4 into here: https://github.com/settings/keys .

6. Ran ssh -T git@github.com and it outputted this:

   Hi AskYous! You've successfully authenticated, but GitHub does not provide shell access.

7. Ran sudo git clone git@github.com:AskYous/google-code-challange.git (a private repository I own). This is when I got the following error:

   Cloning into 'google-code-challange'... Permission denied (publickey). fatal: Could not read from remote repository.

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

8. I checked GitHub and it acknowledges that the key has been used:

Answer 1

The problem was, and I don't know how this happened, is that the private key changed so this new key was not stored on GitHub. It changed somehow. Perhaps I ran the generation process twice.

Answer 2

Just want to help anyone who's experiencing this issue as I spent a while trying to resolve. Make sure the key pairs ownership owned by buildkite-agent
