GitLab: Deploy keys are not allowed to push

Question

I have Existing project folder that contains git , when i need to push it i face this issue

The authenticity of host 'gitlab.com (54.93.71.23)' can't be established.
ECDSA key fingerprint is   
SHA256:HbW3g8zUjNSksFbqTiUWPWg2Bq1x8xdGUrliXFzSnUw.
Are you sure you want to continue connecting (yes/no)?

Note I was working well with git and the same project on fedora 21 but when update to fedora 22 this issue appeared.

Any Suggestions?

Answer 1

Just make sure the host matches what you expect, and that the key fingerprint is what you expect (the key fingerprint should be posted in GitLab's docs), and continue by typing yes and press ENTER

You're seeing this because you've never connected to that host before.
