I ran into an issue where my pinentry was unable to connect, blocking me from
doing commits. You can use this to continue signing commits.
export GPG_TTY=$(tty)
gpg-connect-agent updatestartuptty /bye
printf test | gpg \
--local-user 9A47900E81415D65C32C630066E2BF2B4190EFE4 \
--pinentry-mode loopback \
--sign >/dev/nul
