Plugin is broken. Repository package needs to be updated.
Xubuntu 24.04.2 LTS xfce4-weather-plugin 0.11.2-1build2
This plugin has failed to work for months. It reports "Currently no data available." Apparently this is due to a format change by the weather server. On the Xfce forum, users report that version 0.11.3-1 work. The package in the standard Ubuntu repository needs to be updated. I have been patiently waiting for this to happen for the 24.04 LTS, but it seems as if a nudge is required. Please look into this and push out a working version ASAP. Thanks.
