This seems to be an issue with the key setup on your windows machine rather than a bug in bzr.

If you run try setting the BZR_SSH to the path of your ssh executable then trying to push, what happens? By default, the windows bzr uses paramiko, which only looks for putty's agent pageant for public keys, not in any .ssh folders on your system.

I think we actually do look in $HOME/.ssh or some place like that. I
thought I remembered it being C:/Users/jameinel/.ssh/

IIRC we set that up directly in bzrlib/transport/ssh.py (sftp?)
so it is something we do for our Paramiko connection, not something
that paramiko itself does.

I try set BZR_SSH to c:\Program Files (x86)\Git\bin\ssh.exe, check %BZR_SSH% and try bzr push lp:lge result:
same error message.

What else I can try?

I double check my rsa key pair and it works with git. c:/Users/.../.ssh/ <- here I generate key that work for git(both from console and TortuiseGit) and I try use same key for bzr.

I remove Git (both git console version and TortoiseGit) restart Windows and bzr - works well! )))

Same here: As soon as I installed ToroiseGit and Git console application on my windows system, Bazaar stopped working, showing the same error message as said above.

When trying to uninstall Git, I got a message box: “The following applications use files that need to be removed, please close them”, that within 4 times listed ‘ssh.exe’.

Good thread, particularly the last answers of leanid chaika and Matthias Ronge.

I too had bzr push to stop working suddenly. I tried to set BZR_SSH to my plink.exe path, without improvement (I have set GIT_SSH and SVN_SSH this way).
I didn't want to uninstall Git (I need it to pull projects), so I just went to git/bin and renamed ssh.exe to ssh_git.exe, and suddenly bzr push worked again... :-)
I don't understand why the fact that Bazaar finds ssh.exe in the path makes it to try a different authentication method. :-( (regardless of the BZR_SSH environment variable, apparently).

For the record:

(slightly different message.... Pageant is running, as usual.)
(rename ssh.exe from git/bin)

This should be added to the https://doc.openerp.com/v6.1/developer/01_getting_started/#windows page.

I lost almost an hour tracking this down. There is a conflict with git ssh.exe on windows systems.
