Any additional info

I only change the database password in 0_common.sh

Hmm, interesting. I had no idea it would do that if your time zone configuration was off UTC.

I found this answer

https://stackoverflow.com/questions/38807296/django-1-9-2-assertionerror-database-connection-isnt-set-to-utc

Can you perhaps dig in and see what it takes to fix it in your database configuration files?

I may be able to replicate it but am not sure if your postgresql instance is customized or it was just the setup during installation.

I just went with all the installer defaults from the Ubuntu Bionic minimal install.

We can definitely put in the install guide that the server time should be UTC but we should probably set more guidance than that.

I did not change any database configuration during install vespene. and I solve this problem by change the host timezone from UTC to "Asia/Taipei" using dpkg-reconfigure tzdata not like what you said server time should be UTC .... I dont know if postgresql alter the timezone in postgresql.conf or not , but maybe this is something need to be take care of.

Sorry for the late reply on this one - I think this is something I'll see about adding to the setup guide as something to look into if you hit an error during install. I'll leave this ticket open to track that until I do.

Thanks and hope everything else is going well for you in trying it out!
