我在更新ubuntu到下一个版本后遇到了同样的错误

我刚刚删除了我的sshkey在github帐户，然后重新添加了一个sshkey到该帐户。

如上Alex所说，更改.git/config文件的内容会有所帮助。我也遇到了同样的问题，我想这是因为我更改了我的Github用户名。无法使用更改更新本地文件。所以当你改变你的用户名时，你可能会考虑跑步

Git远程添加原点your_ssh_link_from_github

我希望这对你有所帮助;)

在执行此操作之前，请确保您拥有对回购的写权限。如果您仍然得到错误，请执行以下操作:

Generate a personal access token from your account from Settings > Developer Settings > Personal Access tokens. Keep the token safe somewhere. Go to your repository and run the following: git remote rm origin Then add a new origin along with your username: git remote add origin https://USERNAME@github.com/REPOSITORY_LINK.git Now when you push the code, a prompt will show up asking for your password or personal access token. Paste the token that we generated in the first step in the field, and we're done.

我也有同样的问题。我的问题是误解，我必须先在github上创建空的回购，然后再推到它。哎!包括这个给那些没意识到的人。

Normally it happens because the project is private and you have not rights to write it. I had the same "problem" a few times, and it was for that reason. If the project it is yours, just create a private and a public key following this link: https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent and add them to the "SSH and Key" section on gitHub, then you will be able to push to the repo. In the other hand if the project it is not your, ask the owner to give you the rights for it.

为了解决这个问题(在Linux上)，我只需要运行这个:

git config --global --unset credential.helper
