【问题描述】：
我正在尝试更新自制软件，但我无法连接到 git.. 我看到 https 没有通过，当我尝试 ssh -t 我得到： PTY 分配请求在通道 0 上失败 这些是我的结果表单 ssh -v:

Hi kippelicious! You've successfully authenticated, but GitHub does not provide shell access.

我已经删除了整个 .ssh 文件夹，安装了新的 ssh 密钥，但没有任何效果。
谁能帮忙？
【问题讨论】：
-
阅读消息：“Hi kippelicious！您已成功通过身份验证，但 GitHub 不提供 shell 访问权限。”
-
它是
ssh -T（大写 T），它告诉 ssh 不要打扰 pty 分配，它会抑制您看到的错误消息。 （小写的 t 告诉 ssh 即使您认为不需要它也进行 pty 分配，这保证了错误。）但是，正如@Mat 指出的那样，该错误消息无关紧要：您的测试实际上成功了。 -
另外，GitHub 不是 Git；它是一个存储库托管服务，还为这些存储库提供基于 Web 的界面。
