• Any other interesting things about your environment that might be related
  to the issue you're seeing?

I am using on the same machine WSL, Cmder, Git Bash, SourceTree, Putty Pageant. I did not notice what update start messing up my dev environment. Windows, SourceTree, Git,... But it was working in the near past.

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Git Bash

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

# May be the clone could trigger the issue
git clone git@github.com:git-for-windows/git.git
cd git
# In my case I have only seen it with basically all remote git commands
git fetch

• What did you expect to occur after running these commands?

Doing the job.

• What actually happened instead?

Command failed:

$ git fetch
CreateProcessW failed error:193
ssh_askpass: posix_spawn: Unknown error

I have achieved to fix this issue changing script execution policy. Don't know why but now it works even after having my execution policy back to Restricted.

What I've done:

1. Start PowerShell with administration rights
2. Get my current script execution policy for later

$currentExecutionPolicy = Get-ExecutionPolicy

3. Set it to run local scripts not coming from internet

Set-ExecutionPolicy RemoteSigned

4. Try to fetch an ssh repository
5. (optional) Then restore my previous script execution policy, and it still works!

Set-ExecutionPolicy $currentExecutionPolicy

Don't know if it can help people with the same issue or even if you can somehow fix this issue by warning users or other...

Quite honestly, I am puzzled. Git for Windows' executables are code-signed, on purpose, to prevent something very much like what you are describing...

I am too... 😕

Maybe my "fix" is not the thing that has made the trick but for what I remember it was the only thing I have changed before it has worked again. Maybe SourceTree or something else has messed up my PATH and done strange things with Pageant...

I guess only a very rare corner issue... Not something to worry about.

Okay, then, I'll not worry about it 😄 Thanks for your feedback!
