I have installed Git on Windows 8. The SSH key is uploaded to bitbucket.
Git works well (git status, git commit, etc.)
When I do a pull, git tells me:
$ Git push origin --all -u
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 "and" 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)
By saying yes, he stays is frozen.
I have done the same from SourceTree and passes exactametne same, with the same error message.
In parallel I reviewed Pageant (PuTTY Authentication Agent), and I added the corresponding key (I tested SSH-1 (RSA) and SSH-2 RSA)
In both cases I still have the same problem ... do not let me push. Forever in the same place trying to cache the remote server.
Try connecting to SSH separately first.
With OpenSSH, this would be:
ssh git@bitbucket.org
With PuTTY, you need to use Plink instead:
plink.exe git@bitbucket.org
This should give you the fingerprint prompt separately outside of Git, so hopefully it works then.
