Description Chris Murphy 2019-10-07 16:08:05 UTC 
Description of problem:

After changing Formats from US to Germany and back to US, GNOME Shell appears stuck on Germany.


Version-Release number of selected component (if applicable):
gnome-control-center-3.34.0.1-2.fc31.x86_64

How reproducible:
At the moment its actively reproducing in that the GUI says formats is US but very clearly localectl says otherwise.


Steps to Reproduce:
1. F30 upgraded to F31 via 'dnf system-upgrade'
2. For the lifetime of F30 and F31 up until the next step, the Language and Formats has always been default: English (US) and US (English) respectively; and no changes made on CLI either.
3. GNOME Settings > Formats, change to Germany (German), click Done.
4. GNOME Settings > Formats, change to US (English), click Done.
5. Power off for the night; cold boot this morning....

Actual results:

GNOME Terminal dates and file sizes are all in German.

Expected results:

Should revert back to US English

Additional info:


[chris@flap ~]$ localectl
   System Locale: LANG=en_US.UTF-8
                  LC_NUMERIC=de_DE.UTF-8
                  LC_TIME=de_DE.UTF-8
                  LC_MONETARY=de_DE.UTF-8
                  LC_PAPER=de_DE.UTF-8
                  LC_MEASUREMENT=de_DE.UTF-8
       VC Keymap: us
      X11 Layout: us
[chris@flap ~]$ 

That's with g-c-c Region & Language
Language set to English (US)
Format set to US (English)

So yeah something changed that to DE, but won't change it back to US. mclasen things maybe related to systemd --user
Comment 1 Fedora Blocker Bugs Application 2019-10-07 16:09:59 UTC 
Proposed as a Blocker for 31-final by Fedora user chrismurphy using the blocker tracking app because:

 "All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully and withstand a basic functionality test. "

Language and Formats is certainly basic functionality and so is reverting changed settings. Yet that's clearly broken.

a) Regression
b) GUI got me into this mess, GUI should get me out
c) non-obvious I can use localectl as a work around to reset these variables (untested) rather than doing a clean install
Comment 2 Michael Catanzaro 2019-10-07 16:14:41 UTC 
+1 blocker if other users can reproduce this

Basically once I change Format, it can't be reverted.
Comment 4 Benjamin Berg 2019-10-07 16:40:23 UTC 
The problem is that g-c-c calls the SetLocal DBus method without any of the LC_* variables set. It does so, because the language and format match, in the expectation that localed will unset the variables. However, localed does not do so.

The fix is to just always set the variables to their correct values in set_localed_locale (cc-region-panel.c). localed seems to be smart enough and not show them at that point.

Fixed for me on two systems.
Comment 7 Fedora Update System 2019-10-08 00:28:11 UTC 
gnome-control-center-3.34.1-2.fc31 has been pushed to the Fedora 31 stable repository. If problems still persist, please make note of it in this bug report.
Comment 8 Geoffrey Marr 2019-10-08 06:28:50 UTC 
Discussed during the 2019-10-07 blocker review meeting: [0]

The decision to classify this bug as an "AcceptedBlocker" was made as it violates the following criterion:

"All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully and withstand a basic functionality test" (this counts as 'basic functionality' of the Language and Formats applet)
