My guess is that bacteria down in the crust near thermal vents would live the longest. Thousnands of years if they are able to follow the heat down.
Figure bunkered people might make it a few months depending on their power source and ability to withstand dropping pressure. Not sure how long it would take for the atmosphere to freeze. Government bunker that is vacuum proof with a reactor might make it a decade.
I wonder how long till everyone was dead. And what would be the last living species.
