This question is related to my problem in understanding rebase, branch and merge, and to the problem

How can you commit to your github account as you have a teamMate in your remote list?

I found out that other people have had the same problem. The problem seems to be related to /etc/xinet.d/.

Problem: unable to push my local branch to my master branch at Github

I run

git push origin master

I get

fatal: 'origin' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

The error message suggests me that the branch 'origin' is not in my local git repository. This way, Git stops connecting to Github.

This is strange, since I have not removed the branch 'origin'.

My git tree is

  dev
* master
  ticgit
  remotes/Math/Math
  remotes/Math/master
  remotes/origin/master
  remotes/Masi/master

How can you push your local branch to Github, while you have a teamMate's branch in your local Git?

VonC's answer solves the main problem. I put a passphares to my ssh keys.

I run

$git push github master

I get

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

It seems that I need to give the passphrase for Git somehow.

How can you make Git to ask passphares?
