Tom:
Thank you for your response. I was aware of this issue which is the
reason that I asked if there was a way around it. The thread does not
seem to indicate a solution.
Assuming there is a workaround, how to upgrade without losing the
configuration (weewx.conf) and the previous data in the database, etc.
One of the reasons that I would like to update to 4.1.1 is the greater
number of temperature inputs in the schema. I have run out of
temperature inputs and still have four or five more to add. I assume
that I can add to the 3.92 database setup but I am a hardware designer
and am afraid of messing thing up in Linux and Python and so forth.
If there is no solution to using owfs under Python 3, how do I install
4.1.1 and specify to use Python 2?
Thanks for your help in getting this resolved.

I have Weewx 3.92 running on a Raspberry Pi3 using One-Wire
sensors for all measurements via a USB to 1-Wire interface
(DS9490). The Pi is running Buster and I installed Weewx using the
Debian installation package. Everything is now working fine and I
want to tempt fate by upgrading to Weewx 4.1.1 (and Python 3).
What is the easiest and most reliable way to do this? Do I just
install Weewx again on the same Pi using the procedure for an
initial install of the Debian package? Will it keep the database
and conf files or do I have to save them and put them back when
done? Do I need to do anything with OWFS to work with Python 3?
Should I follow the procedure in installation guide:
Tell your system to trust weewx.com <http://weewx.com>:
wget -qO -http://weewx.com/keys.html | sudo apt-key add -
For Debian10 and later, use python3:
wget -qO -http://weewx.com/apt/weewx-python3.list | sudo tee
/etc/apt/sources.list.d/weewx.list
Basically, how best to upgrade without losing the old data and
keeping things working?
Thanks for any guidance.
Michael
