New setup failing - no access methods

[IanHobson]

My machine lost ts magic smoke, so I have had to restore to a temporary machine (windows).  The sources are on a Linux VM, (restored) with a share. 

Therefore I work in windows, editing sources via the share. 

To save the changes, I use gitgui to set up the commit (done) and the push. 

However the push is failing, and git gui refused to save the fingurprint (bug??). 

So I set up a putty session, using SSH and stored the fingerprint.  

Now it is failing with "FATAL ERROR: No supported authentication methods available (server sent: publickey) fatal: Could not read from remote repository." 

What do I need to set up? I'm guessing it is something for git on the windows end, but I know not what. 

I do have password access to bitbucket, so I can get into the account. 

More info. I had not set up .ssh under my new user, and then found I could not read the keyfile (on the restored D: drive).  Now I get this....

ian@ganymede MINGW64 /d/TempFiles/Temp4
$ git clone git@bitbucket.org:coachmaster/coachmaster.git
Cloning into 'coachmaster'...
FATAL ERROR: No supported authentication methods available (server sent: publickey)
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

ian@ganymede MINGW64 /d/TempFiles/Temp4
$ ssh -T git@bitbucket.org
authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled

ian@ganymede MINGW64 /d/TempFiles/Temp4
$

Ideas anyone?

The answer is that git has changed the way it discovers how to drive SSH! 

The magic incantation is to enter

git config core.sshCommand "ssh -i ~/.ssh/id_rsa"

into the git bash terminal (opened in the directory above the .git). Clearly your id file may be different. 

This adds the text in quotes to the [Core] section of .git/config
