无法使用 SSH 密钥克隆 Gitlab 私有存储库。密钥身份验证无效。 ssh-keys

我有一个默认密钥对存储在.ssh文件夹下，并已将id_rsa.pub添加到https://gitlab.com/profile/keys，但仍无法使用此密钥访问GitLab。

ssh -vT git@gitlab.com

无法登录：

我的配置

cat /etc/ssh/ssh_config

$ cat /etc/ssh/ssh_config
Host *
    SendEnv LANG LC_*

将以下内容添加到空的~/.ssh/config中并没有帮助：

Host gitlab.com
    Hostname gitlab.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa

我的钥匙为什么不管用？

根据调试跟踪，您的客户端向服务器提供了 .ssh/id_rsa，但服务器没有接受。这可能有几个原因。例如，您的 id_rsa.pub 文件可能与 id_rsa 文件不匹配，因此您使用了错误的公钥设置 github。 - Kenster

你可以执行 eval $(ssh-agent -s)，然后执行 ssh-add ~/.ssh/id_rsa 再试一次吗？我记得这曾为我解决过类似问题。如果这样还不行，尝试删除你的RSA密钥（如果你没有用它做其他事情），然后按照这些说明重新开始创建一个新的密钥对。 - Anton

我不能删除这个密钥，因为我在其他服务中使用它。我创建了一个自定义的密钥：gitlab_id_rsa。我添加了它：ssh-add ~/.ssh/gitlab_id_rsa

$ ssh-add -l 4096 SHA256:BU0W1JRLgxvBPyXSYZ7qphRelLAECdDyvlAJndR1+4k denys2@DENYSs-MacBook-Pro.local (RSA) 2048 SHA256:x3OEhLg/QPPUvr1f4IPo0+uHv8q73Da1TGjUnzD8FdQ denys@DENYSs-MacBook-Pro.local (RSA)

更新了~/.ssh/configIdentityFile ~/.ssh/gitlab_id_rsa但没有解决问题。我的第二台电脑上也有同样的问题。 - Denis
