ValueError: Incorrect timezone setting: US/Pacific - it seems the minimal ubuntu server only has official time zones like America/Los_Angeles in this case - the US/Pacific is an old alias which is not used any more.

Questing - why is it visible in the dropdown list of selected timezones in the first place? How come Python script has more info than system timezones???
