• What actually happened instead?
• I received the following dialog
  
• It has a text box but no instructions for what I should enter
• I do not know what to expect if I select okay
• It does a good job telling which keys are an issue and where they can be found, but offers no help as to the best solution

Ah, I see what's happening. When we wrote git-askpass we didn't quite expect the questions that OpenSSH would ask to be this long. The prompt from OpenSSH gets cut of at the input field. The full uncropped prompt seems to continue with

Are you sure you want to continue connecting (yes/no)?

So the underlying ssh is expecting you to enter either yes or no in there.

As to the concrete problem pointed out by the error message, and how to deal with it, see https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/

I've made some progress with resizing the dialog according to the length of the prompt, now I just need to figure out why the pushbuttons are behaving the way they are.
