我正试图从我的BitBucket帐户克隆一个回购到我的Windows 10笔记本电脑(运行GitBash)。我已经完成了连接所需的所有步骤(设置我的SSH密钥，通过成功SSHing git@bitbucket.org验证，等等)。然而，每当我试图克隆一个回购，提示不断挂断后，确认我想要缓存Bitbucket的密钥。
User@Laptop MINGW64 /C/Repos
$ git clone git@bitbucket.org:mygbid/test.git
Cloning into 'test'...
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n) y
没有文件被克隆，结果是一个空的repo。试图从这个repo启动一个git pull origin master也要求缓存键，然后挂起没有反馈。尽管我在测试SSH时没有请求缓存密钥，但git操作总是在每次失败前都请求密钥。
由于没有可以处理的错误消息，我真的不知道哪里出了问题。我尝试过多次回购，包括非常小的回购，但都没有成功。
如果你使用KiTTY(而不是PuTTY)，它有-auto-store-sshkey参数。
因此，你可以将GIT_SSH_COMMAND(或git config——global core.sshCommand)设置为c:/KiTTY/klink.exe -auto-store-sshkey。
输出仍然包含关于新键和问题的信息，但它不会等待答案:

要做到这一点，从powershell打开一个powershell窗口，并粘贴如下:
echo y | & 'C:\Program Files (x86)\GitExtensions\PuTTY\plink.exe' -ssh git@github.com
echo y | & 'C:\Program Files (x86)\GitExtensions\PuTTY\plink.exe' -ssh git@gist.github.com
echo y | & 'C:\Program Files (x86)\GitExtensions\PuTTY\plink.exe' -ssh git@bitbucket.org
或使用PuTTY独立版本:
echo y | & 'C:\Program Files (x86)\PuTTY\plink.exe' -ssh git@github.com
echo y | & 'C:\Program Files (x86)\PuTTY\plink.exe' -ssh git@gist.github.com
echo y | & 'C:\Program Files (x86)\PuTTY\plink.exe' -ssh git@bitbucket.org
另外值得知道的是，putty将已知的主机存储在注册表项下:
HKEY_CURRENT_USER\SoftWare\SimonTatham\PuTTY\SshHostKeys
你可以把下面的文件放到。reg文件中并运行:
