"icon file not found" icon shown for weather applet; tooltip is "broken clouds", at night

[adrnde]

Expected behaviour

Should be showing partial cloud icon perhaps with a partial moon

Actual behaviour

showing rectangle with red slashed circle; temperature displayed correctly beneath
Mouseover brings up city with "broken clouds" as expected

Steps to reproduce the behaviour

Weather Report 1.24.0, on fresh install of Linux Mint 20
Need "broken clouds" as weather.
Switched to diff city with clear weather, shows moon sliver
Trying different cities:
overcast, shows two overlapping clouds
mist shows wavy lines, as expected
As of when trying this, Nov 6 02:00 EST, Trondheim, Norway also had 'broken clouds',
and also displayed the broken icon

What icon theme are you using? We have a set of "weather-few-clouds" icons in the default mate icon theme which menta inherits from as well. Looking at the "weather.c" source file in libmateweather(where these icons are chosen) shows this block:

    case SKY_BROKEN:
    case SKY_SCATTERED:
    case SKY_FEW:
	if (daytime)
	    return "weather-few-clouds";
	else {
	    icon = g_stpcpy(icon_buffer, "weather-few-clouds-night");
	    break;
	}

meaning the "weather-few-clouds" or "weather-few-clouds-night" icon which we provide should display unless you are using an icon theme that does not provide it and does not inherit from mate-or you have found a bug in libmateweather.

I've seen such problems with weather icons in Ubuntu-MATE, but not always: sometimes icon present, sometimes not

@ssrublev the icon shown in your screenshot belongs to indicator-datetime.

Tracking days when the weather icon works / does not, icons go missing at night under conditions of "few clouds" or "broken clouds".

It looks like the icon folder "Mint-X" is the one being used, and it does have an icon for
weather-few-clouds-night.

On occasion the weather app will not update at all, instead just sitting in 'updating' status indefinitely. The text based "weather" from package "weather-util", which gets data from the same source, always works. Perhaps there is some fiddling detail in the received data that isn't always what is expected?

[rbuj]

@adrnde There may be several reasons which may prevent fetching weather data. If the command line application weather from weather-util package cannot get the weather data it uses a cache to display the last successfully captured data.

The weather applet sets the "Updating..." tooltip just before updating the weather information:

mate-applets/mateweather/mateweather-applet.c

Line 521 in e712870

gtk_widget_set_tooltip_text (GTK_WIDGET(gw_applet->applet), _("Updating..."));

It's updated only if it's able to retrieve valid data:

mate-applets/mateweather/mateweather-applet.c

Line 442 in e712870

gtk_widget_set_tooltip_text (GTK_WIDGET (gw_applet->applet), s);
