What ssh-agent you are using?

Dear Alexander Belchenko：

Nice to meet you.
I use bzr-2.2.0-setup.exe , download from Bazaar Web Site.
http://wiki.bazaar.canonical.com/Download
Do you have any solution ?
thanks for your help.

One bug here is that we probably shouldn't give a traceback when paramiko.SSHException is raised.

@rhfan, the question is, are you using putty or any other ssh-related software?

Do you have pageant?

Hello!

I have similar problem. With-out pageant a have one response:
bzr: ERROR: Connection error: Unable to authenticate to SSH host as
  <email address hidden>

If I run pageant then I get:

Run command: bzr branch lp:jukebox/trunk T:\Devel\2011_Bzr\der\trunk
Connected (version 2.0, client Twisted)
bzr: ERROR: paramiko.SSHException: lost ssh-agent

bzr 2.2.1 on python 2.6.4 (Windows-post2008Server-6.1.7600)
arguments: ['C:\\Program Files (x86)\\Bazaar\\bzr.exe', 'qsubprocess', '--bencode', 'l6:branch16:lp:jukebox/trunk27:T:\\Devel\\2011_Bzr\\der\\trunke']
encoding: 'cp1251', fsenc: 'mbcs', lang: None

Reproduced on x64 machine. Other workstation has no problems on Windows 7 x86.

The problem is reproduced when pageant.exe is executed by Administrator account.

If I run pageant.exe by myself everything is ok.

Is this related to bug #736955?

Well detected Jon, that does seem to be the root cause. Unfortunately upstream paramiko is pretty dead, so we may have to carry patches for the Bazaar win64 install to get fixed.
