Bail out! GWeather:ERROR:../libgweather/gweather-location.c:207:location_ref_for_idx: assertion failed: (db)
Aborted gnome-calendar
$ apt search gnome-calendar
gweather-locations/unstable 2026.2-2 amd64
location data for libgweather
sudo apt install gweather-locations solved the problem so gnome-calendar
needs to pull in gweather-locations if it is not found.
