Hi
Been trying to get Weewx running on Ubuntu 19.10 but problems...
This how it looks (directly after weewx is started).
m@ubuntu1910n:~$ sudo systemctl status weewx

Jan 14 00:08:34 ubuntu1910n systemd[1]: weewx.service: Succeeded.
Seems we are using the wrong startup type in the unit configuration file
for the systemd. We should be using forking.
https://www.freedesktop.org/software/systemd/man/systemd.service.html
*"If set to simple, the service manager will consider the unit started
immediately after the main service process has been forked off. It is
expected that the process configured with ExecStart= is the main process of
the service.""If set to forking, it is expected that the process configured
with ExecStart= will call fork() as part of its start-up. The parent
process is expected to exit when start-up is complete and all communication
channels are set up. The child continues to run as the main service
process, and the service manager will consider the unit started when the
parent process exits."*

About the PIDFile path: *"The path specified typically points to a file
below /run/.*" This behouvior is changed since systemd 240. A warning is
issued otherwise:
*"Line references path below legacy directory /var/run/, updating
/var/run/weewx.pid → /run/weewx.pid; please update the unit file
accordingly."*
Ubuntu 19.10 then works fine (also Debian10 Buster and Ubuntu 19.04).
