   git config --global --unset gpg.program
   git config --global --add gpg.program /usr/bin/gpg
   

3. Enable Commit Signing

   

4. Commit

   

5. Open Git Log

   > git -c user.useConfigOnly=true commit --quiet --allow-empty-message --file - -S
   error: gpg failed to sign the data
   fatal: failed to write commit object
   > git config --get-all user.name
   > git config --get-all user.email
   

6. Show Command Output

Same issue here. I am on Windows10 using SSH and developing on Fedora. The following gets it to work, but the steps must be repeated every time you re-open VSCode.

1. Manually run export GPG_TTY=$(tty)
2. Run echo "test" | gpg2 --clearsign enter password
3. You can now perform signed commits using the Terminal and VSCode GUI. (If code signing is enabled / setup)

If you don’t do step 1 and go straight to step 2, you get this error;

gpg: signing failed: Inappropriate ioctl for device
gpg: [stdin]: clear-sign failed: Inappropriate ioctl for device

I can confirm the problem. I am using remote SSH from a Windows machine developing on a Linux machine. I have export GPG_TTY=$(tty) in my .profile. But I have to manually export it in the console and sign something once in the console (e.g. echo "test" | gpg2 --clearsign) to be able to use VSCode to use signed git commits.
