Install Opera without confirmation to update with system. I am trying to do unattended installs of Opera and it sits there for confirmation of yes to update with system repos. I have tried many things to accomplish this.

This is currently what I am using to install the package using dpkg

echo PASSWORD | sudo -S dpkg -i /home/user/System/Packages/Opera/opera-stable_56.0.3051.52_amd64.deb

I have tried many things, but the latest answer I can find is this however it does not work for some reason.

echo yes Y | sudo -S dpkg -i /home/user/System/Packages/Opera/opera-stable_56.0.3051.52_amd64.deb

Any help with this is greatly appreciated.
