Ubuntu – gnome-software on Ubuntu 16.04 doesn’t work

16.04gnome-softwaresoftware-center

After plain installation of Ubuntu 16.04 LTS gnome-software doesn't work.
It has opened once with GUI, but installation of Unity Tweak Tool didn't finish.

When starting again, GUI doesn't come up.
When opening from terminal, a warning appears, but the application GUI doesn't open.

$ gnome-software
(gnome-software:7052): Gs-WARNING: failed to open plugin /usr/lib/gs-plugins-9/libgs_plugin_xdg_app_reviews.so: /usr/lib/gs-plugins-9/libgs_plugin_xdg_app_reviews.so: cannot open shared object file: No such file or directory

Does anybody have same experience, and eventually, a solution?

According to the recommendation:

$ dpkg-query -S /usr/lib/gs-plugins-9/libgs_plugin_xdg_app_reviews.so
gnome-software: /usr/lib/gs-plugins-9/libgs_plugin_xdg_app_reviews.so

Proposed reinstall of gnome-software did not help.

As workaround, use Synaptic Package manager and command line.

Perform these steps to Fix gnome-software/ubuntu-software

Rename or remove the ~/.local/share/gnome-software. In the steps below it's removed and will be recreated when you start gnome-software. It currently has a list of what has been installed. The first line will ensure the locked up instances are removed from memory. Might not be necessary.

$ killall gnome-software
$ rm -r ~/.local/share/gnome-software

Now run ubuntu-software or gnome-software from the Unity Launch Button.
