Hi, I had the same problem with gnome-software not starting at all. I found a solution that worked for me here: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1606238/comments/12
what Ibrahim is suggesting is to remove all files in ~/.local/share/gnome-software and then the application will start.
