Comment 9 for bug 1640741

Hi,
Hi,
Hi, is it really fixed?

I've installed clean Ubuntu GNOME 17.04 (Zesty Zapus) and have the same issue. When you download any .deb file like Chrome, Virtualbox and etc and double click on it - it opens Software Center. But clicking on Install button does nothing. But if you select any app from Software Center, for example Caffeine - Install button works just fine. So the issue is only with downloaded .deb files. If you try to use Gdebi for the same files - everything works fine.

I've tried reinstalling it by doing:

$ sudo apt-get --purge remove gnome-software
$ sudo apt-get install gnome-software

But the problem remains.

$ lsb_release -a

Description: Software Center for GNOME
 Software lets you install and update applications and system extensions.
 .
 Software uses a plugin architecture to separate the frontend from the
 technologies that are used underneath. Currently, a PackageKit plugin provides
 data from a number of traditional packaging systems, such as rpm or apt. An
 appdata plugin provides additional metadata from locally installed data in the
 appdata format.
