Hi Tom,
thanks for that tip.
I managed to downgrade to 4.10.2 in the meantime to re-gain my weather station.
I will try your workaround next weekend.
Take care
Frank

Betreff: Re: [weewx-user] weewx 5.0 upgrade trouble
This is a problem with the Fine Offset driver that we're aware of. It's
caused by the deprecation of the function datetime.utcnow() in Python 3.12.
The fix for now is to downgrade to Python 3.11.

Hi there,
OK, I have taken the risk in updatting weewx from 4.10.2 to the latest 5.0
(beta) version.
I followed the update guide and everything looked fine.
When finally starting the service I am getting the following error:
Nov 21 12:03:52 raspi weewx[18165] CRITICAL __main__: **** TypeError:
can't subtract offset-naive and offset-aware datetimes
So, it looks like some data is time-zone aware and some is not.
Basically I found something to cure the problem, but as I have no idea on
programming, I need some help...

Here is the full log down to the error message...
