Comment 0 for bug 1688721

I received this error when trying to install local file google-chrome-stable.deb version 58.0.3029.96-1.
This is using gnome-software 3.22.7-0ubuntu3.17.04.2 from zesty-proposed. Other times, the installation process just hangs at some percentage. I am testing this gnome-software version due to Bug LP:#1672424.
The same file was successfully installed with gdebi.
