[email protected]: Permission denied (publickey)

问题：

no such identity: /Users/weixiongwei/.ssh/github_ed25519: No such file or directory
			[email protected]: Permission denied (publickey).
			Could not read from remote repository.
			Please make sure you have the correct access rights
			and the repository exists.

解决方案：

生成密钥对

ssh-keygen -t ed25519 -C "[email protected]"

Note: If you are using a legacy system that doesn't support the Ed25519 algorithm, use:

ssh-keygen -t rsa -b 4096 -C "[email protected]"

This creates a new SSH key, using the provided email as a label.

> Generating public/private algorithm key pair.

1. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

   > Enter a file in which to save the key (/Users/you/.ssh/id_algorithm): [Press enter]

2. At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases."

   > Enter passphrase (empty for no passphrase): [Type a passphrase]
   > Enter same passphrase again: [Type passphrase again]

 将本机生成的ssh key复制到个人GitHub账户中去。

本机账户文件夹下找到id_rsa.pub，以text方式打开，复制内容。

新增 SSH 密钥到 GitHub 帐户

要在 GitHub.com 上配置帐户以使用新的（或现有的）SSH 密钥，还需要将密钥添加到帐户。

MacWindowsLinux

GitHub CLIWeb browser

在将新的 SSH 密钥添加到 GitHub.com 上的帐户之前，您应该具有：

• 检查现有 SSH 密钥
• 生成新 SSH 密钥并添加到 ssh-agent

在向您在 GitHub.com 上的帐户添加新 SSH 密钥后，您可以重新配置任何本地存储库以使用 SSH。 更多信息请参阅“将远程 URL 从 HTTPS 转换为 SSH”。

Note: GitHub improved security by dropping older, insecure key types on March 15, 2022.

As of that date, DSA keys (ssh-dss) are no longer supported. You cannot add new DSA keys to your user account on GitHub.com.

RSA keys (ssh-rsa) with a valid_after before November 2, 2021 may continue to use any signature algorithm. RSA keys generated after that date must use a SHA-2 signature algorithm. Some older clients may need to be upgraded in order to use SHA-2 signatures.

1. 将 SSH 公钥复制到剪贴板。

   如果您的 SSH 公钥文件与示例代码不同，请修改文件名以匹配您当前的设置。 在复制密钥时，请勿添加任何新行或空格。

   $ pbcopy < ~/.ssh/id_ed25519.pub
   # Copies the contents of the id_ed25519.pub file to your clipboard

   提示：如果 pbcopy 不可用，可找到隐藏的 .ssh 文件夹，在常用的文本编辑器中打开该文件，并将其复制到剪贴板。

2. 在任何页面的右上角，单击您的个人资料照片，然后单击 Settings（设置）。

   

3. In the "Access" section of the sidebar, click  SSH and GPG keys.

4. 单击 New SSH key（新 SSH 密钥）或 Add SSH key（添加 SSH 密钥）。

   

5. 在 "Title"（标题）字段中，为新密钥添加描述性标签。 例如，如果您使用的是个人 Mac，此密钥名称可能是 "Personal MacBook Air"。

6. 将密钥粘贴到 "Key"（密钥）字段。

   

7. 单击 Add SSH key（添加 SSH 密钥）。

   

8. 如有提示，请确认您的 GitHub 密码。

   

ssh -T [email protected]

如果出现下面的问题： 

 解决方案：

ssh-add -k ~/.ssh/id_rsa

 如果出现下面的问题： 

 解决方案：

sudo chmod 0600 ~/.ssh/id_rsa

再次执行：

ssh -T [email protected]

如下图则配置成功
