Cannot control GnuPG from shell (IPC parameter error)

[Seby]

Hello,

I have a script that interacts with GnuPG in an automated / unattended
way, but it cannot control the keyring. I keep getting this:

gpg: key generation failed: IPC parameter error

I am running 2.3.0-beta82. I tried to search for this error and I
could only find clues that lead to gpg-agent, but # gpg-agent --help
doesn't allow me to disable it. What is the good approach here?

Thanks in advance.
