The command below reserrects the hidden "Software Updater" window when issued. It does not fix the underlying coding issues however it makes it possibly to continue the update process without killing/quitting - restarting the app.
sudo apt-get install wmctrl # if necessary wmctrl -R 'Software Updater' after issuing the command the window should appear and respond to its controls as normal. Hope this help...
