git pull and fetch fail with "fatal: The remote end hung up unexpectedly"

From cygwin git on Win7 I'm trying to coordinate with my linux workstation. Both were cloned from the same upstream repository. First I do a "git fetch origin", then try to fetch from my workstation.

$ git fetch origin
[... all ok ...]
$ git fetch b

fatal: index开发者_Go百科-pack failed

Cygwin's ssh.exe has this bug. Replace cygwin's ssh.exe with ssh.exe from a msysgit install, and this problem will go away.

How did you create your keys?

With cygwin's git or with the mingw git in git bash?

I believe the real problem is that cygwin's ssh looks for .ssh in /home/name/.ssh and mingw's git ssh looks for .ssh in c:/user/name/.ssh

Chances are your keys are in one and only one of these directories.

You can trying telling cygwin's .ssh to use a different identity file using the -i switch, or move the keys into both directories, or create an ssh config file in /home/name/.ssh/config.

I created a config that contains:

Host github.com
    User jerryasher
    Hostname github.com
    IdentityFile c:/Users/jerry/.ssh/id_rsa

And given that I can use either the mingw git from git bash or cygwin's git from an rxvt to interact with github.
