ok - under UB - I saw the restart button after installing. Clicking on it restarted UB - then I saw updates installing via plymouth on a reboot ... it rebooted again and there are no more updates.
Note - for UB our default is not to have updates via gnome-software (we hide by overriding the org.gnome.software updates key - we use Ubuntu's software updater
FYI - works as expected under UB
