Public bug reported: About halfway through, Software Updater hangs "Installing updates..." I didn't have Details expanded to see where it hung.
journalctl contains some potential reasons for the hang: Jun 03 12:21:18 - gnome-session[1678]: debconf: unable to initialize frontend: Gnome Jun 03 12:21:18 - gnome-session[1678]: debconf: falling back to frontend: Dialog Jun 03 12:21:18 - gnome-session[1678]: debconf: unable to initialize frontend: Dialog Jun 03 12:21:18 - gnome-session[1678]: debconf: (TERM is not set, so the dialog frontend is not usable.)
