Gnome Software Center won't open - 16.04
The 16.04 Gnome Software Center will not open. When I click the icon on the launcher, all it does is show the loading icon and... that's it.
I looked it up, and nothing is working. I didn't even do anything either, it's just not opening. This is a fresh install from today. I first clicked the "Try Ubuntu" option when I got it working, and it would open, but since I actually installed it, it won't open.
After typing in the terminal apt policy software-center gnome-center, I got this:
software-center:
Installed: (none)
Candidate: (none)
Version table:
gnome-software:

And after typing software-center, it gave me
The program 'software-center' is currently not installed. You can install it by typing:

and after typing gnome-software, it didn't show anything.

Could someone please help me? Thank you.
Solution 1:
this problem can be solved by deleting the file ~/.local/share/gnome-software. It will be recreated when you start gnome-software. So just make sure you do not have any running instances of ubuntu-software or gnome-software:
$ killall ubuntu-software
$ killall gnome-software
and then:
$ rm -r ~/.local/share/gnome-software
