PS. please double-check that the public key you upload on trac is id_rsa.pub and not the other key. And it seems that you might have gssapi on (in /etc/ssh/ssh_config or in ~/.ssh/config ?), and it is broken somehow. Could you try running
ssh -k -vvv g...@git.sagemath.org (-k disables gssapi) And finally, IIRC you can use https authentication to push to trac. By the way, do you have a github account, and if yes, are you able to push branches there via ssh?
