Installed application from .deb does not appear unless Ubuntu is restarted

It seems that the process does not exit when the gnome-software window is closed.

If I kill the gnome-software process and restart it, the freshly installed .deb package is now visible in the list. It's better than rebooting but still quite confusing.

Status changed to 'Confirmed' because the bug affects multiple users.

Problem verified with Google Chrome on Yakkety.
 * install google-chrome-stable package with g-s;
 * close and restart g-s, notice that Google Chrome is not listed under "installed" apps nor searchable inside g-s;
 * $ pkill gnome-software;
 * start again g-s, now Google Chrome is listed in g-s.

However there is one omore problem: I can launch Google Chrome from g-s, but I can't remove it. "Remove" button in g-s does nothing.

This seems to occur for packages that are not in the Ubuntu archive e.g.
https://www.google.com/chrome/
http://itch.io/app

Robert, the last time I checked, this issue doesn't affect Ubuntu 17.10 "artful"

I tried with Ubuntu 17.10 and a .deb package I propose here: http://psydk.org/pngoptimizer

The application does not appear unless gnome-software is killed.
After I restart gnome-software, it appears in the Graphics section and if I specifically search for it. However it does not appear in the "Installed" view.

(valid bug, but not one the team will commit to fixing for 17.10)

Ubuntu 18.04, gnome-software 3.28.1

The application now appears in the "Installed" list, but with the wrong name and the wrong icon.
If I kill gnome-software and restart it, the application is not present anymore in the "Installed" list.
If I do a search in gnome-software, I can find the application again, with the right icon and with the "Installed" check tick (as it was the case for 17.10).
