Ubuntu Github ssh 密钥问题

Question

我遵循了本指南中给出的每个步骤： http://help.github.com/linux-key-setup/

当我完成时，我可以 ssh 到 git@github.com，得到响应：

通道 0 上的 PTY 分配请求失败 嗨亚历克斯巴拉诺斯基！您已成功通过身份验证，但 GitHub 不提供 shell 访问权限。 与 github.com 的连接已关闭

但是当我去克隆我的仓库时，它失败了：

权限被拒绝（公钥）。 致命：远端意外挂断

我经常使用 Github，但这是我第一次在 Ubuntu 计算机上使用它，这里有什么我遗漏的吗？

非常感谢任何帮助。

Answer 1

您是否以 root 身份运行了 Github 指南中的所有命令？鉴于您已经提到的解决方案，这是我目前可以想象的唯一方案。

在任何方面，以 root 身份工作都是极其危险的，应尽可能避免。

我强烈建议以您自己的用户身份重新运行这些说明。我支持 Ray 的建议，即使用 -v 再次尝试，我们可以从那时起为您提供帮助。完全使用root，特别是对于这种开发+推送过程，是很危险的。您只需删除一棵树 (rm -rf tree*) 并意外在树和 * 之间添加一个空格，bam，大量内容丢失。你也可以做得更糟。

ssh 可能会尝试多个密钥，直到找到一个有效的密钥。 （令人困惑但稳健）

在详细模式下：

ssh -v git@github.com

您将看到 ssh 使用哪个密钥进行身份验证。

然后您可以重新设置密钥或将正确的文件名添加到主机 github.com 的 ~/.ssh/config

干杯

我在一台新配置的 Ubuntu 机器上，必须确保我的 SSH 密钥配置正确。 http://help.github.com/linux-set-up-git/
