I have a GitHub account that I am now unable to sync with my local repo.

Each time I try to push/pull/fetch changes to the repo, the ssh client just returns without printing any error messages and definitely without pushing the changes to the remote repo.

As an example: 

$git push origin master
Enter passphrase for key '/home/sriram/.ssh/id_rsa':

sriramshankar@EHSriram /cygdrive/i/work/workspace/myProject

This is the output observed on a Cygwin terminal. Can anyone help me out with resolving this issue?

UPDATE:
I tried implementing more traces. It seems I am authenticated to the server but then it just abruptly stops:

  • What version of git are you using. – VonC Jun 20 '16 at 08:01
  • I am using `git version 2.8.2` – Sriram Jun 20 '16 at 08:16
  • https://github.com/englishhelper/EHCloud does not exist though – VonC Jun 20 '16 at 08:17
  • It does. It is a private repo. – Sriram Jun 20 '16 at 08:20
  • @VonC: Funny thing is, I am seeing this issue for every single repo I own. Might it have something to do with global config settings? – Sriram Jun 20 '16 at 08:22
  • OK, I suppose this is cygwin related.try in a git bash or in a classic CMS session. – VonC Jun 20 '16 at 08:22
  • @VonC: That was the issue. Committing etc. works well from within the Git Bash shell but not cygwin. Any ideas on where I should look for what went wrong? – Sriram Jun 22 '16 at 09:35
  • Not sure: Cygwin should not be needed here. Git bash itself comes with 400+ Linux commands (that you can even use from a regular CMD shell). – VonC Jun 22 '16 at 09:42
  • The issue was reported before: http://stackoverflow.com/q/28190018/6309. Maybe an ssh config issue? http://stackoverflow.com/a/20627106/6309 – VonC Jun 22 '16 at 09:44

Start by:

You can have more traces with:

GIT_TRACE_PACKET=true git push
# or
GIT_SSH_COMMAND="ssh -v" git push

The OP Sriram confirms in the comments:

That was the issue. Committing etc. works well from within the Git Bash shell but not cygwin.

  • Thank you for your reply. I can see (please see update to question for more details) with traces on that the server authenticates me but then just terminates the connection.. – Sriram Jun 20 '16 at 08:15
  • How do I enable more traces method using Git Bash? Git Bash opens in the Windows Power Shell for me. – Sriram Jun 20 '16 at 08:57
  • No it does not, it opens abash shell – VonC Jun 20 '16 at 10:02
  • @Sriram Go to `C:\path\to\git\PortableGit-2.9.0-64-bit\bin` and type `bash --login -i`: you will get a GNU bash, version 4.3.42(5)-release. – VonC Jun 20 '16 at 10:16
