Details

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

**

• I've been trying to run the executable from cmd.exe and powershell, but the result is the same. Exit code 0, and there is no other output on stdout.
  **

• 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.

C:\Program Files\Git\bin>bash

C:\Program Files\Git\bin>sh

C:\Program Files\Git\usr\bin>.\ls.exe

C:\Program Files\Git\usr\bin>.\whoami.exe

C:\Program Files\Git\usr\bin>ssh-keyscan github.com

C:\Program Files\Git\usr\bin>

Any Linux command like bash, ls, ssh, any of these .exe files return the exit code 0 and print nothing else. I wanted to clone a project over ssh, but I think it's not working because of this problem.

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

** I was expected to have them work as they work outside of docker, on a windows machine. **

• What actually happened instead?

** they returned exit code 0 and printed nothing to stdout/console **

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

** insert URL here **

I wonder if you are using the tar.gz version of git or .exe to install git? I also saw the same problem but only happened when I use the tar.gz version. If I install git with the exe ( through chocolatey ) it is ok.

[paul-grozav]

I've installed git through chocolatey. Here is a more detailed way to reproduce the problem:

I also read issue 813, but I did not find a solution to the problem. Also seems related to issue 1403.

Does the native Win32 port of OpenSSH (https://github.com/PowerShell/Win32-OpenSSH) help?

[dscho]

I'll stop holding my breath for an answer.

[manvscode]

Wow. Was this ever resolved? I am experiencing the same problem.

[paul-grozav]

@dscho Sorry for not seeing your messages. For some reason I saw @manvscode 's message in my SPAM. I guess your messages ended up there, and I missed them.

I didn't try the "the native Win32 port of OpenSSH". The workaround I found back then in 2018 was to:

:: === Install chocolatey (to install Visual C++ Build Tools CLI)
powershell -NoProfile -ExecutionPolicy unrestricted -Command "(iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))) >$null 2>&1"
powershell -command "[Environment]::SetEnvironmentVariable('Path', $env:Path + ';C:\ProgramData\chocolatey', [EnvironmentVariableTarget]::Machine)"
set PATH=%PATH%;C:\ProgramData\chocolatey

:: === Install openssh & git (for cloning/resolving dependencies with conan)
:: Git-for-windows is not working with it's own ssh client. see issue:
:: https://github.com/git-for-windows/git/issues/1737
:: I have to install openssh
choco install -y openssh
powershell -command "[Environment]::SetEnvironmentVariable('GIT_SSH', 'C:\Program Files\OpenSSH-Win64\ssh.exe', [EnvironmentVariableTarget]::Machine)"
set GIT_SSH=C:\Program Files\OpenSSH-Win64\ssh.exe
powershell -command "[Environment]::SetEnvironmentVariable('Path', $env:Path + ';C:\Program Files\OpenSSH-Win64', [EnvironmentVariableTarget]::Machine)"
set PATH=%PATH%;C:\Program Files\OpenSSH-Win64

[dscho]

Hehe... that GIT_SSH setting is the native Win32 port...
