Seems to work for me. If you have multiple SSH keys on your system,
make sure that you are connecting using the correct key for
identification. This is done by running `ssh -i <identity_file>`
where `<identity_file>` is the full path to your SSH private key.

You can also add this permanently to your local SSH client
configuration, typically found in `~/.ssh/config`. This allows
per-site SSH client configuration, for example:

Host git.sagemath.org
Hostname git.sagemath.org
IdentityFile /path/to/correct/ssh-private-key

Ensure also that you have gone to
https://trac.sagemath.org/prefs/sshkeys and supplied your *public*
key.

sorry but it is still not working

have you created an ssh key pair? What is the output of

ls -al ~/.ssh/

?

You still need to provide a host to connect to. In your screenshot
(posting screenshots is not necessary, you can just copy/paste the
terminal output), you just ran `ssh -i ~/.ssh/id_rsa`. I didn't say
this explicitly but it was implicit that that's just one flag to ssh;
other options still need to follow. That said ~/.ssh/id_rsa is the
default so if that's really the correct SSH key you shouldn't need to
provide it. Did you provide trac.sagemath.org your public key as I
suggested, and if so what exactly did you do?

Hey I am facing a similar problem in configuring git with trac using the

git trac config --user USERNAME --pass 'PASSWORD

command given in this link but ssh authentications fails.

while using 

git trac config --user USERNAME --pass 'PASSWORD

I get this error:

Saved trac username.

Saved trac password.

Trac xmlrpc URL:

    https://trac.sagemath.org/xmlrpc (anonymous)

    https://trac.sagemath.org/login/xmlrpc (authenticated)

    realm sage.math.washington.edu

Using token-based authentication with the provided JWT token

generated by the Trac server.  If a username and password were

configured as well, the token takes priority.  To unset the

token use:

    git trac config --token=

I suggest that you try creating a small git repo on github and try to push to it and pull from it. If it doesn't work then you have a problem with a firewall or something like that.

I couldn't push into a test repository in github the error was

remote: Invalid username or password.

fatal: Authentication failed for 'https://github.com/diveshkr-code/Testing-git.git/'

it's probaly because my remote origin in .git/config is different than my url(it is somehow set to https://github.com/cubeton/mynewrepository.git guess I fucked up somewhere) how do i change this?

Could you push a branch using "plain" git?
Assuming the output of

git remote -v

contains "trac g...@trac.sagemath.org:sage.git (push)"

you should be able to push a branch like this:

git push trac HEAD:u/gh-diveshkr-code/test1
