Looks like the method name changed from Thread.isAlive() to Thread.is_alive(). They must have completely eliminated the old name with Python 3.9.

In weewx/engine.py, line 776, change this

if self.thread and self.thread.isAlive():

to this:

if self.thread and self.thread.is_alive():

Just realized that there are many other places where the old name isAlive() is used. You may have to change other lines as well.

I changed all occurrences of isAlive to is_alive, and so far (30 minutes) it appears to be working. Since it always died quite quickly, before (within 5 minutes) I tentatively conclude this was the only hiccup in the upgrade. Thanks for the quick response!

Hi

Yes, Debian Bullseye now installs Python 3.9.1 and the wheels fall of weewx as you discovered. I ran a sed -i -e 's/isAlive/is_alive/g' `find /usr/share/weewx -name '*.py'` and it indeed fixes it.
