Can synaptic ignore Unauthenticated packages?

[yurenju]

hi all,

i want to use synaptic to install my package just like gnome-app-install. but my repository is Unauthenticated. apt-get can use this to avoid:
apt-get --allow-unauthenticated --force-yes --y install <something>

when i use this synaptic paramater:
sudo synaptic --hide-main-window --non-interactive \
--set-selections-file="something.txt" \
-o APT::Get::Assume-Yes=true \
-o APT::Get::force-yes=true -o APT::Get::AllowUnauthenticated=true

but it also pop the NOT AUTHENTICATED warning... (see attachment )

does any parameter can do auto install without check authenticated?
