It seems to be unable to set "verbose" to 0 using gpgconf on gpg.
Package: gnupg2 Architecture: i386 Version: 2.0.11-0kk1
gpgconf --list-options gpg | grep verbose
verbose:4:0:Detaillierte Informationen:0:0::::1
So the FLAG is 4=lists which means that it can have several values.
The VALUE=1 so one verbose is set, which is consistent with the contents
of gpg.conf-2 that is used here.
How do I set this VALUE=0 with gpgconf?
According to the documentation this should be the following, which fails:
echo "verbose:0:0" | gpgconf --change-option gpg
gpgconf: argument for option verbose of type 0 (none) must be positive
gpgconf: fatal error (exit status 1)
