git: fatal: Could not read from remote repository

git: fatal: Could not read from remote repository :

Your ssh key most likely had been removed from ssh agent

ssh-add ~/.ssh/id_rsa

where id_rsa is a ssh key associated with git repo

Update

You may get Could not open a connection to your authentication agent. error to resolve that you need to start the agent first by:

eval `ssh-agent -s`

I was facing same issue a while ago…

my .git/config had

url = [email protected]:manishnakar/polymer-demo.git

I replaced it with

url = https://github.com/manishnakar/polymer-demo.git 

and it works now:)


You can specify the username that SSH should send to the remote system as part of your remote’s URL. Put the username, followed by an @, before the remote hostname.

git remote set-url website [email protected]***.com:path/to/repo

Make sure you have correct url in .git/config

url = [email protected]:username/repo.git

If it’s your first push, you’ll need to set up correct upstream

$ git push -u origin master

You can check which key is used by:

$ ssh -vvv [email protected]

The reply should contain something like this:

debug1: Next authentication method: publickey
debug1: Offering RSA public key: ~/.ssh/id_rsa
...
You've successfully authenticated, but GitHub does not provide shell access.

Also it’s possible to define rules for ssh in ~/.ssh/config, e.g. based on aliases:

   Host github
      HostName github.com 
      User git
      IdentityFile "~/.ssh/id_rsa"

   Host git
      HostName github.com 
      User git
      IdentityFile "~/.ssh/some_other_id"

You can set connect to different ports, use different username etc. for each alias.
