Git -从远程服务器提取时拒绝权限(publickey)

Question

我在Windows上运行WSL2。在本地，在WSL2中，我可以毫不费力地推/拉到远程Github存储库。

当我通过相同的SSH密钥SSH到远程服务器时，我连接成功。但是，一旦在远程服务器上尝试运行git pull，就会收到permission denied (publickey)错误。即使使用ssh -t [e-mail]，我也会收到错误。

我试着在~./ssh中调整我的配置文件:

Host *
AddKeysToAgent yes
IdentityFile ~/.ssh/id_rsa
Host abc.theserver.com
User theuser
ForwardAgent yes

我的公钥在远程服务器的authorized_keys文件中。我可以SSH成功，但我不确定为什么git拒绝

密钥ssh -Tv [e-mail]的输出为:

根据ssh -Tv [e-mail]的输出，看起来Ubuntu服务器没有使用转发的代理凭证。这表明下列一个或多个条件为真:

1. ssh-agent没有在WSL2实例上运行
2. WSL2配置不允许代理转发
3. Ubuntu服务器不允许代理转发

https://docs.github.com/en/authentication/connecting-to-github-with-ssh/using-ssh-agent-forwarding#troubleshooting-ssh-agent-forwarding有一些关于如何检测和纠正这些潜在问题的建议(尽管您可能需要与Ubuntu服务器的管理员进行礼貌的对话)。
