GPG signing commits over ssh

edit ✏️

I was editing some blog posts over ssh, when I ran into this error. gpg was failing to sign my commits. I realized that this was because I could not answer to the desktop keyring over ssh, but had no idea how to fix it.


This is the error message I was seeing.

gpg failed to sign the data ssh

The fix

The fix ended up being pretty simple, but quite a ways down this stack overflow post . This environment variable tells gpg that we are not logged into a desktop and it does not try to use the desktop keyring, and asks to unlog the gpgkey right in the terminal.

export GPG_TTY=$(tty)

The log in menu

This is what it looks like when it asks for the passphrase.

enter your passphrase to unlock your gpg key
