Ubuntu – Unable to install Opera browser on Ubuntu 17.04

I tried to install opera by downloading the .deb file from opera website. Running sudo dpkg -i opera-stable_44.0.2510.1218_amd64 gave the following results:

Opera is currently not available in Ubuntu software store or in Software Boutique. I also tried older opera-stable_44.0.2510.857_amd64.deb and got similar results. I downloaded the package twice thinking it might be any download error but same result.
