github 访问拒绝访问推送

Question

您好，我正在学习 an rails app 的初学者教程.但是我在推送存储库时遇到问题。每次我执行 git push -u 到 origin master 时，我都会遇到这个错误。

guinslym@ubuntu:~/Documents/rails_tuto/first_app$ git remote add origin https://github.com/guinslym/first_app.git
fatal: remote origin already exists.
guinslym@ubuntu:~/Documents/rails_tuto/first_app$ git push -u origin master
Warning: Permanently added the RSA host key for IP address '192.30.252.130' 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.

这里我确实设置了一个私钥来使用，但是当我想要推送时我仍然有错误。我确实遵循了这个 stackoverflow answer (第一个答案)

guinslym@ubuntu:~/.ssh$ ls
id_rsa  id_rsa.pub  known_hosts
guinslym@ubuntu:~/.ssh$ ssh -i id_rsa.pub -vT git@github.com
    ...

如果您需要将 ssh url 更改为远程“来源”的 http，请使用:

git remote set-url origin https://guinslym@github.com/guinslym/first_app.git

它会在 git push 上询问您的 GitHub 密码。
