The template gives a choice (no choice) of 18.04-LTS but the Create hits an error after a minute or so 'TLJH requires Ubuntu 20.04 or higher'. I tried again by editing the Template and Parameters in 3 locations to read 20.04 (only choice) but this bombed as well... "changing property 'imageReference' is not allowed" (me:rob5@uw.edu)
