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.

Seen this fix going around, it worked for me:

sudo apt-get autoremove gnome-software
sudo apt-get install gnome-software

It appears if you just reinstall gnome-software it just works!

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.

I had to go into file manager as root

sudo -H nautilus

Then move all the files from /usr/lib/gs-plugins-9 to a temp folder and delete ...reviews.so

I then opened gnome-software and it loaded empty.

Moved all the .so files back and opened successfully to install new software again finally!

I too got this error. I did 

$ ps -aux | grep gnome-software

and found that there was already a process running. (I believe this may be because I had tried to invoke it from the launcher and it had failed, but that much is a hunch.)

I killed the process. I then ran gnome-software again in the terminal and got: 

(gnome-software:6912): Gs-WARNING **: Failed to create permission org.freedesktop.packagekit.trigger-offline-update: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.freedesktop.packagekit.trigger-offline-update is not registered

(This may be the real reason it had failed but left a process running.)

I then did:

$ sudo apt update
$ apt-get install -f --reinstall gnome-software

The icon on the launcher now works and brings up the new software centre.

the installation of lubuntu software center (over synaptic or with terminal and sudo apt install lubuntu-software-center worked for me - at least I have now one working software center.
