Upgraded OS and Weewx - fails to start

[Steve Fowler]

Just upgraded to Debian 12 and installed the latest version of weewx according to the install steps for Debian.  Everything seemed to go along smoothly until the end and I get this:

Job for weewx.service failed because the control process exited with error code.
See "systemctl status weewx.service" and "journalctl -xeu weewx.service" for details.

systemctl and journalctl both point to weewxd not finding module user.extentions.

Any help would be appreciated.

Which 'latest' ?  v4 or v5 beta ?

Which instructions ?

[Steve Fowler]

Followed the instructions for Debian install using deb package in the weewx docs for python 3.  It downloaded the latest stable 4.10.2.  I installed using root and not the weewx user if that makes and difference. The system has python 3.11.2. 

[Steve Fowler]

Looks like I got it running by going back and running setup.py.  Whatever failed in the deb package install was corrected and the service started.

I had the same problem with OpenSuse Tumbleweed where a big update even blocked python-based system programs such as firewalld (it's not nothing), others and of course weewx.

I was able to check all the programs for errors with the command:

# systemctl list-units --state=failed

I made a link from python3.11 to python3 which is the reference for many programs:

# ln /usr/bin/python3.11 /usr/bin/python3

All programs worked again while avoiding changes in all files.

I hadn't posted it, but after installing weewx it failed to create the weewx web folder in /var/www/html directory.  Instead it ended up in weewx home.  So I created a link.

Entirely expected behaviour, you indicated you did a setup.py install and by default setup.py installs result in WeeWX generated output going to /home/weewx/public_html. Where to find things in the User's Guide refers. Creating the link was exactly the correct solution.
