Is there a pinentry program that Oracle recommends or provides for Solaris 10? gpg-agent man page states "Please make sure that a proper pinentry program has been installed". I have gpg-agent (GnuPG) 2.2.11 installed on Solaris 10.
This is the error I get when I attempt to create a key without a pinentry program:
gpg: agent_genkey failed: No pinentry
Key generation failed: No pinentry
