Steps to Reproduce:

1. Try to commit with gpg key while host is mac with keyboxd

After the last fix for this I still could not get it to work. I can see the agent is working in the container and reads the keys though.

I also tried this with the latest ubuntu image with the latest gpg version and setting "use-keyboxd" in ~/.gnupg/common.conf in the dev container. It doesn't matter what it finds the right key but throws "No such file or directory".

I should add my gpg key is password protected.

Does this issue occur when you try this locally?: Yes/No Does this issue occur when you try this locally and all extensions are disabled?: Yes/No

Please check in the dev container:

Does signing without Git work:

echo "test" | gpg --clear-sign

Check if the config is correct:

git config --global user.signingkey
git config --global gpg.program

Thanks for helping me with this, maybe I'm just doing something wrong, I keep getting that same error:

> echo "test" | gpg --clear-sign

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

test
gpg: signing failed: No such file or directory
gpg: [stdin]: clear-sign failed: No such file or directory

Shows my correct key:

git config --global user.signingkey
14:32:07.720173 git.c:463               trace: built-in: git config --global user.signingkey
XXXXXXXXXXXXXX

This command returns nothing inside dev container and on the host: git config --global gpg.program

I said before my key is password protected. I fought with a ton of pinentry settings, but nothing I do seems to work I keep getting that "No such file or directory" error in the dev container.

I have pinentry-program /opt/homebrew/bin/pinentry-mac in my local ~/.gnupg/gpg-agent.conf.

Please also append the Dev Containers log from when this happens. (F1 > Dev Containers: Show Container Log)
