LANG errors after recent update

I’ve been noticing this warning/error after a recent update. Now everything I run pacman -Syu I get a lot of these warnings:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "",
        LC_ALL = (unset),
        LC_ADDRESS = "en_US.UTF-8",
        LC_NAME = "en_US.UTF-8",
        LC_MONETARY = "en_US.UTF-8",
        LC_PAPER = "en_US.UTF-8",
        LC_IDENTIFICATION = "en_US.UTF-8",
        LC_TELEPHONE = "en_US.UTF-8",
        LC_MEASUREMENT = "en_US.UTF-8",
        LC_TIME = "Default.UTF-8",
        LC_NUMERIC = "en_US.UTF-8",
        LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to a fallback locale ("en_US.UTF-8").

running sudo locale-gen doesn’t get rid of the warnings

EDIT: at the same time I started noticing Aislesriot Solitare stopped running with a LANG problem.

[jim@den-pc ~]$ sol
Non UTF-8 locale (ANSI_X3.4-1968) is not supported!
[jim@den-pc ~]$ 

What are the contents of /etc/locale.gen? Also, what does localectl show?

[jim@den-pc ~]$ localectl
   System Locale: LANG=en_US.UTF-8
       VC Keymap: us
      X11 Layout: us
[jim@den-pc ~]$
[jim@den-pc ~]$ cat /etc/locale.gen
# Configuration file for locale-gen
#
# lists of locales that are to be generated by the locale-gen command.
#
# Each line is of the form:
#
#     <locale> <charset>
#
#  where <locale> is one of the locales given in /usr/share/i18n/locales
#  and <charset> is one of the character sets listed in /usr/share/i18n/charmaps
#
#  Examples:
#  en_US ISO-8859-1
#  en_US.UTF-8 UTF-8
#  de_DE ISO-8859-1
#  de_DE@euro ISO-8859-15
#
#  The locale-gen command will generate all the locales,
#  placing them in /usr/lib/locale.
#
#  A list of supported locales is included in this file.
#  Uncomment the ones you need.

Also, what DE are you using?

Plasma KDE

That looks normal.

:thinking:

Also in KDE System settings, it only has one language and it’s American English

Let me update one of my KDE VMs and see if anything is broken with recent updates.

It’s done that to me in the past, months ago, too.

Good thing: Fallback locale.

Where is this coming from? A KDE speciality?

At this point most things are still fine due to the fallback. Except for sol

No, all my KDE machines have a normal settings there or it is unset:

>> env | grep LC                                                                                                                      [130]
LC_TIME=en_US.UTF-8
>> env | grep LC
>>                                                                                                                     [130]

That could be the issue though.

What does it show in System Settings->Regional Settings->Formats?

Yeah, here LC_TIME is as expected, not Default.UTF-8.

Change the setting for Time to be en_US.UTF-8.

Then logout and back in to see if it fixes anything or not.

latest pacman update was fine and no LANG warnings.

Thanks for the help. Not sure what changed the setting. Wasn’t me.

If you did as suggested… :point_down:

then this was what fixed it, explicitly setting the malformed setting (“Default” locale value is not existent).
KDE has a long history on this issue, because of using Qt (long story).
There was a related recent fix merged, but I don’t know if it’s in the repo packages yet.
