I updated gnome-software and libappstream-glib and restarted. I downgraded gnome-calculator. Gnome-software updated updates and found update for g-c, but when I click on Download button it just blinks and nothing happens (even pkmon shows no action). So I can't update because there is still Download button and there is no 'Restart & update' button. With this version I'm unable to update.
Works fine. I updated anaconda on live and installed the system.
