Bug Description

Ubuntu GNOME 16.04.3
gnome-software 3.20.5-0ubuntu0.16.04.5

Not being able to install 3rd party deb's is a very serious regression.

Test Case
Visit in Firefox and download Chrome.
Open with "Software Install"
The Ubuntu/GNOME Software app should start and show you a basic page about Google Chrome
Click Install.
Google Chrome should install itself

What Happens
The Install page does show up.
After clicking the Install button, the button changes to Installing for a few seconds and then changes back to Install.
Google Chrome is not installed.
There is no PolicyKit authentication prompt to install software.
When I run gnome-software --verbose, Progress says 9% which I think is when it would ask for authentication.

Regression Potential
This fixes a High Impact bug.
And the fix is minimal:

Other Info
I am setting the importance of this bug to critical according to #7 of
