somewhere between 296793637b22bdb4d23b479879eba0a71c132a66 and 83cbad92d73216bb0d9187c56cce0b91f9121d5a my gpg (which uses a yubikey to do the signing) stopped working. Signing commits, or even “echo ‘asdf’ | gpg --sign”, no longer appear to work (for the former I see just “error: gpg failed to sign the data”, for the latter “gpg: signing failed: Invalid ID”).
I’ll bisect further later, but right now it’s great that I can just roll back and continue to be productive until I have time to figure out what happened in more detail
