Issue

after following all steps, gpg-agent reports write-env-file is obsolete

gpg-agent[666]: /home/pi/.gnupg/gpg-agent.conf:4: obsolete option "write-env-file" - it has no effect
gpg-agent[666]: WARNING: "--write-env-file" is an obsolete option - it has no effect

Suggested Fix

I'm unsure as I'm trying to setup gpg authentication for the first time
