Re: [Fab-user] SSHException with Ubuntu 9.04

[Jeff Forcier]

Thanks for confirming this, both of you. I also note that Pat
McNerthney just (as in <10 minutes ago) actually investigated this and
put a nice, detailed comment on Robey's Paramiko Github page outlining
what's going on:

    
http://github.com/robey/paramiko/commit/f573017a1d56c0ef9fdb08598bf4a43f40c01952

It's unfortunate that 1.7.4 is no longer available on PyPI either; if
Robey isn't able to push out a 1.7.6 or 1.7.5.1 soon I can't think of
much else to do for new users other than to direct them to the
Paramiko site to download a .tgz of 1.7.4.

In the meantime, hopefully it's obvious to anyone reading this that
they should hold off on upgrading to Paramiko 1.7.5 until this is
resolved :)

-Jeff
