Executing ssh on cygwin under windows 10 recently started failing, after many years of stable logins. The relevant output from ssh under a mintty from Xwindows:

Host key verification failed.
The special file /dev/tty is there:
% ls -la /dev/tty

I updated Cygwin to make sure all the binaries were the latest. Also windows updated itself earlier this week.
I'm a little baffled as to what might be going on. Clues gratefully accepted.

Documenting my solution in case anyone else has the problem: It appears that a Windows version of OpenSSH was introduced in the 2018 spring update, and it is being called instead of Cygwin's ssh. (See e.g. https://www.zdnet.com/article/openssh-arrives-in-windows-10-spring-update/)
% which ssh
/cygdrive/c/WINDOWS/System32/OpenSSH/ssh
The reason for the sudden problem with ssh is that the cygwin PATH has /cygdrive/c/WINDOWS/System32 ahead of /usr/bin/. Or at least, mine did.
So the issue is solved by calling /usr/bin/ssh explicitly. (Reordering the PATH is also a possible solution, but not for my environment.)

Cygwin has an openssh package that must be installed to get the ssh client and ssh client tools.

As other comments have hinted at, you must also installopenssh, as it is not installed by default.
– timelmer
Dec 5 '18 at 4:27
if you install openssh (by re-running cygwin installer and selecting the openssh package), "which ssh" command should switch to show "usr/bin/ssh" instead of "cygdrive/c/WINDOWS/..." (without any additional manual path reordering)
