Hi @Nicholas,
The issue you're facing stems from the configuration of GPG signing in Git, specifically with the command `!git config --global gpg.x509.program smimesign`. This command is intended to specify a program for signing commits using S/MIME (Secure/Multipurpose Internet Mail Extensions), but if 'smimesign' is not available or installed on your system, Git will throw an error indicating that it cannot find the signing program. To resolve the issue with signing commits in Git using S/MIME, make sure that the `smimesign` program is installed on your system. This program is not included with Git by default and needs to be installed separately. Depending on your operating system, you may need to look for specific packages or tools that provide S/MIME signing capabilities. After verifying the installation of `smimesign`, confirm that your Git configuration is correctly set up to use it, check your current Git configuration with:
git config --list
Look for entries related to GPG and make sure they reflect your intended setup. After following these guidelines, if you continue facing issues with S/MIME then I will recommend consider switching to GPG (GNU Privacy Guard) for signing commits since it is widely supported and might offer a smoother experience. Please let me know if you have any further questions.
