MINGW Windows - curl 7.59.0 missing sftp lib

Question

I've install new version of msysgit and MINGW, but there is not support for sftp?! Could you please help me to add this?

$ curl -V

when I try access to sftp: fatal: Protocol 'sftp' not supported by curl, exiting...

Answer 1

I found the solution. I just download some other curl.exe file and replace it in

C:\Program Files\Git\mingw64\bin

SFTP work, but then there was another error.

fatal: Could not get last commit. Network down? Wrong URL? Use 'git ftp init' for the initial push., exiting...

So I've run with -v option: git ftp push -v

error was: curl: (51) SSL peer certificate or SSH remote key was not OK

At last I've run ssh-keyscan hostname.example.com >> ~/.ssh/known_hosts from here

But it isn't help me, so I just use parameter --insecure and it works nicely now.
