Weewx on Raspi 4

[Alan Salmon]

Has anyone tried installing this python3-weewx_5.1.0-3_all.deb on a fresh install of the latest Raspian OS (Bookworm) with all updates applied as of yesterday?

Attempting to do so gives me a range of errors, including messages like this in /var/dpkg.log:

2024-08-11 18:15:00 startup packages configure
2024-08-11 18:15:00 configure weewx:all 5.1.0-4 <none>

2024-08-11 18:15:54 startup packages configure

Attempting to run the configuration script simply crashes with a number of errors ending with:

  File "/usr/share/weewx/weectllib/station_actions.py", line 250, in config_altitude
    float(value)
ValueError: could not convert string to float: ''
dpkg: error processing package weewx (--configure):
 installed weewx package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 weewx
E: Sub-process /usr/bin/dpkg returned an error code (1)

Can anyone suggest where to start looking before I build a new Raspi OS and start again, please?

I suspect that your debconf variables got contaminated with a bad value for altitude. You can see what they are with

  sudo debconf-show weewx

If there's a bad value, try purging weewx (sudo apt purge weewx), then reinstalling.
