I recently switched back to using gnome 3 when I did a fresh install of Fedora 25 -- Which, I've been super happy with!. Last night I started a new project on github and did my first code push. And this popped up:
What is this?? Bro, you're killing my commandline flow!
$ env |grep --color SSH SSH_ASKPASS=/usr/libexec/openssh/gnome-ssh-askpass
$ unset SSH_ASKPASS
I would suggest adding that to your .bashrc if you'd like to make the fix more permanent
