i searched on google for solution but nothing ,i have uninstall and
installet again but the same, i tryed here
Managing SSH Keys | Heroku Dev Centerhttps://devcenter.heroku.com/articles/keys#
but
the same problem ,can anyone help?

The problem is likely nothing to do with your git install. It directs
more
toward your SSH keys.

If you are using Google, type the following line into the search box.

site:heroku.com ssh

It should give you better Google results. Namely, likely the Heroku
“Managing Your SSH Keys | Heroku Dev Center” link.
