fixing `gpg failed to sign data` error on macOS

gpg_fix.txt

For troubleshooting, two things to first try:

run `git config --global gpg.program gpg2`, to make sure git uses gpg2 and not gpg
run `echo "test" | gpg2 --clearsign`, to make sure gpg2 itself is working
If that all looks all right, one next thing to try:

run `brew install pinentry` to ensure you have a good tool installed for passphrase entry
If after that install and you re-try git commit and still get the "failed to sign the data" error:

run `gpgconf --kill gpg-agent` to kill any running agent that might be hung
If that says gpgconf isn’t installed or doesn’t have a `--kill` option, you might try this:

`cp ~/.gnupg ~/.gnupg-GOOD` to save a copy of your `~/.gnupg` to revert to later if needed
`brew install gnupg21` to install `GnuPG 2.1`
The reason for saving a copy of your `~/.gnupg` dir is that GnuPG 2.1 potentially creates/changes some key data in way that isn’t backward-compatible with GnuPG 2.0 and earlier, so if you want to go back later, you can do `mv ~/.gnupg ~/.gnupg21 && mv ~/.gnupg-GOOD ~/.gnupg`.

Otherwise there are some basic steps to run to check you’ve got a working GnuPG environment:

run `gpg2 -K --keyid-format SHORT`, to check that you have at least one key pair
If the output of that shows you have no secret key for GnuPG to use, then you need to create one:

run `gpg2 --gen-key`, to have GnuPG walk you through the steps for creating a key pair

i highly suggest this gist , everything goes well now

need to change from 'brew install gnupg21' to 'brew install gnupg2'

run gpgconf --kill gpg-agent to kill any running agent that might be hung

In my case (zsh on MacOS Catalina), all I needed to do to fix this was add to this to my .zshrc: export GPG_TTY=$(tty).

Thanks for the tip.

Thanks @Shosta. It solved me

gpgconf --kill gpg-agent was what worked for me

gpgconf --kill gpg-agent

Worked!

gpg --list-keys
git config --global user.signingkey [my pub hash key]
worked for me

gpgconf --kill gpg-agent

worked for me after upgrading to big sur

Thank you for this. I'm a returning Mac user and this was causing me some headaches after the Big Sur upgrade.

worked for me. My mac OS Big Sur.

Thanks all

I upgraded brew and I got

gpg: signing failed: No pinentry
gpg: [stdin]: clear-sign failed: No pinentry

gpgconf --kill gpg-agent worked for me too. Thanks for the tips!

killed gpg agent and also exported that env var. Still no joy...

This works!
export GPG_TTY=$(tty) then source ~/.zshrc

stack overflow thread has nothing on this gist!!!

In Debian 10, worked out well:

export GPG_TTY=$(tty)
source ~/.bashrc

the gpgconf --kill gpg-agent command saved my day Thank you!!!!.

for me, remove the gpgsign: true in git config --global -e works, lol

Thank you! It worked for me.
