Eset gateway security "The package is of bad quality"

I am trying to install Eset Gateway Security on my 64 bit server and I get "The package is of bad quality"

Lintian check results for /home/administrator/Downloads/esets-3.0.22.amd64.deb:
E: esets: maintainer-address-missing www.eset.eu/support

And when I installed it both times, couldn't boot up afterwards and had to reinstall Ubuntu.
