我正在尝试拉取远程服务器上的 git repo（使用 SSH 远程 URL）。在我的家用电脑上，我有一个正在运行的 SSH 代理：
PS user@PC> ssh-add -L
ssh-ed25519 AAAAC3NzaC1lZDIASDE5AAAAIP69b6DHAqQgKVZWNnhbSbhBXG1OH3yePiAHfdyTU+f1 user@PC
当我通过 ssh 连接到服务器（ForwardAgent yes在 ssh 配置中使用）时，我仍然看到相同的密钥：
PS user@PC> ssh server
user@server> ssh-add -L
ssh-ed25519 AAAAC3NzaC1lZDIASDE5AAAAIP69b6DHAqQgKVZWNnhbSbhBXG1OH3yePiAHfdyTU+f1 user@PC
但是，尽管我已将此公钥上传到我的 bitbucket 个人资料，但连接到 bitbucket 仍然不起作用：
user@server> ssh -vvv [email protected]

什么原因导致与代理商沟通出现错误？
答案1
昨天我在 VSCode 中尝试将密钥转发到远程服务器时也遇到了同样的问题。结果发现默认安装太旧，与服务器的协议不兼容。
以下是我解决问题的方法：
以提升的权限打开
PowerShell。使用以下命令卸载默认安装：
Remove-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0（可选）如果您看到类似 的内容，请重新
UninstallPending启动NotPresent。检查默认的OpenSSH是否已完全卸载：
Get-WindowsCapability -Online | Where-Object Name -like 'OpenSSH*'仅安装最新客户端：
winget install Microsoft.OpenSSH.Beta --override ADDLOCAL=Client或关注使用 MSI 安装 Win32 OpenSSH如果你没有
winget。检查安装并验证版本>=
8.9.1.0：Get-Command ssh-agent（可选）
ssh-agent如果服务尚未启动，则启动它。Start-Service ssh-agent Set-Service ssh-agent -StartupType Automatic Get-Service ssh-agent（可选）将以下行添加到
%USERPROFILE%/.ssh/config：Host server ForwardAgent yes AddKeysToAgent yes
