Missing locale causes `DateFormat` to throw an exception #1659

Snubletunge · 2024-04-29T16:52:23Z

When I choose an app in the Ubuntu App Center, it won't show details about the app, or the information images just flash for a moment.

** (snap-store:17779): WARNING **: 18:43:14.817: atk-bridge: get_device_events_reply: unknown signature
flutter: Another exception was thrown: Instance of 'DiagnosticsProperty'

I have tried to reinstall Ubuntu, but the issue persist.

Thanks for the report - could you provide the log files from $HOME/snap/snap-store/current/.local/share/snap-store and the output of glxinfo -B to help diagnose possible rendering issues?

Feichtmeier · 2024-04-30T14:49:55Z

This looks like the error widget in release mode :) (a widget that flutter draws when something went wrong)
Could you start snap-store from the terminal and provide any errors / outputs / exceptions here?

Snubletunge · 2024-04-30T17:28:13Z

Here is the error message when running the snap from terminal:

And another when I start snap-store from Terminal, and select an app from the main page (Transmission) to view in the store:

OK, so the locale nn (Norwegian nynorsk) that I am using, is crashing this, changed to the locale nb (Norwegian bokmål) and the store works as it should.

Still seems something is off when I run it from Terminal:

$ snap run snap-store
Gtk-Message: 19:46:14.151: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it.

d-loose · 2024-05-06T15:09:52Z

Thanks for providing those additional details. The issue seems to be that, even though the proper localization delegates for nn_NO and others are provided by ubuntu_localizations, they're only available if the corresponding locale is listed in the supportedLocales for the MaterialApp. With our current setup that requires the existence of the respective .arb file. I'm adding nn_NO through weblate to see if that solves the problem for this specific locale. I'll keep this issue open though, since we should find a proper solution for all cases.

mguinhos · 2024-06-04T06:16:34Z

Also having this problem.

d-loose · 2024-06-04T08:26:02Z

Also having this problem.

Which locale are you using? Are you seeing a similar error message when running snap-store from the terminal?

mguinhos · 2024-08-31T18:13:27Z

@d-loose

flutter: INFO appstream: Unsupported locale: und. Defaulting to "en".

its saying my locale is und.

d-loose · 2024-09-02T16:06:12Z

its saying my locale is und.

That means the locale is 'undetermined', so either the flutter framework has problems parsing your locale, or there's already something broken in your system setup. In either case, we should handle this case properly.

Could you post the output of

locale

as well?

mguinhos · 2024-09-02T18:08:28Z

Sure,

$ locale
LANG=pt_BR.UTF-8
LANGUAGE=pt_BR:
LC_CTYPE="pt_BR.UTF-8"
LC_NUMERIC="pt_BR.UTF-8"
LC_TIME="pt_BR.UTF-8"
LC_COLLATE="pt_BR.UTF-8"
LC_MONETARY="pt_BR.UTF-8"
LC_MESSAGES="pt_BR.UTF-8"
LC_PAPER="pt_BR.UTF-8"
LC_NAME="pt_BR.UTF-8"
LC_ADDRESS="pt_BR.UTF-8"
LC_TELEPHONE="pt_BR.UTF-8"

@d-loose

d-loose · 2024-09-05T19:50:06Z

Seems like Flutter doesn't parse LANGUAGE=pt_BR: correctly. The resulting locale is 'und' in this case. Both pt_BR and pt_BR:pt work correctly though.

@robert-ancell I suppose this happens at the level of the engine - do you know more?

robert-ancell · 2024-09-10T22:48:58Z

We used g_get_language_names in the engine instead of writing our own parser with the hope this would do the right thing... However it seems to make both duplicate and empty locales; parsing LANGUAGE=pt_BR: returns "pt_BR", "pt", "", "C". I suspect the empty string is confusing Flutter and making the "und" locale.

robert-ancell · 2024-09-10T22:51:45Z

Sigh, and LANGUAGE="pt_BR: :" also returns " " and "".

robert-ancell · 2024-09-10T23:16:06Z

See flutter/engine#55091, this should hopefully improve things.

d-loose · 2024-09-11T08:13:34Z

Great, thanks a lot for digging into this!

We're seeing issues with and "und" (undefined) locale and exceptions in applications (see ubuntu/app-center#1659). It seems the GLib method for getting the language names doesn't clean up invalid values, so we should do that.
