UPDATE
Now I realize I cannot access the file folder/manager. This is bad. Help!
Odd issue here. I like using Gnome-Usage app for stopping the Software Center (and for seeing what is running, etc).
However, I cannot open it for some reason. I tried uninstalling it and re-installing it multiple time. No dice. I then tried running it in terminal and here is the error message I received:
** (gnome-usage:3049): WARNING **: 15:37:19.865: game-mode.vala:95: GameMode D-Bus error: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name com.feralinteractive.GameMode was not provided by any .service files
(gnome-usage:3049): Gtk-WARNING **: 15:37:20.004: HdyLeaflet does not have a child property called allow-visible
Any help?
