To complete the post above, I tested the command : "sudo systemctl restart
udev weewx"
ps aux|grep weewxd issues now:
pi@raspberrypi:~ $ ps aux|grep weewxd
weewx 11862 7.0 0.9 46012 18772 ? Ss 09:26 0:00 python3
/usr/share/weewx/weewxd.py /etc/weewx/weewx.conf
pi 11883 0.0 0.0 7460 572 pts/3 S+ 09:26 0:00 grep
--color=auto weewxd
But weewx still fails to start with the same error...
