Annoying perl locale warnings

Every time I run some commands, which I guess are perl scripts, I get these a

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "",
        LC_ALL = (unset),
        LC_ADDRESS = "en_US.UTF-8",
        LC_IDENTIFICATION = "en_US.UTF-8",
        LC_MEASUREMENT = "en_150.UTF-8",
        LC_MONETARY = "es_ES.UTF-8",
        LC_NAME = "en_US.UTF-8",
        LC_NUMERIC = "en_US.UTF-8",
        LC_PAPER = "en_US.UTF-8",
        LC_TELEPHONE = "en_US.UTF-8",
        LC_TIME = "en_150.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").

How do I get rid of these, and also, whose bug is this so I can report it to the right bug tracker?

This is the output of localectl:

localectl                                                                                                                                  ✔ 
   System Locale: LANG=en_US.UTF-8

This is my /etc/locale.gen (which of course I never touched):

 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.

And these are the settings in System Settings → Regional Settings, which are the only thing I touched (and these are the configurations that I need and want):

Having read the post you linked, I have no idea where to go from here.

The issue is your time, Currency and Measurement settings in your Formats.
Since you only have en_US.UTF-8 enabled you get this error.

2 ways to go from here:

  • Delete ~/.config/plasma-localerc in your user profile. This will reset all the settings to default (en_US) in System settings > Format . Once deleted you the error in shell should be gone.
  • Enable all locales in system which you would need for settings of time, currency, measurement

Actually I see also en_US.UTF-8 is commented out:

Since you only have en_US.UTF-8 enabled you get this error.

And how did that happen? If I select those settings in KDE’s Format settings, why doesn’t it enable whatever needs to be enabled, or at the very least warn me that I need something that is not there?

Enable all locales in system which you would need for settings of time, currency, measurement

How do I do that?

User profile settings do not change your system-wide settings.

Use Manjaro Settings Manager it should be installed on your system. You can enable all the locales you need.

Ok, so, the options I find there don’t match the ones I have in KDE’s settings.

For example, in KDE, for Time I have “en_150.UTF-8” which, when you search for it, is found under “Engligh (Europe)”. That’s exactly how I want dates to be displayed, because it gives me the months and days in English, 24-hours time (I hate the AM-PM thing), and it gives me “day/month/year” (I’m fine with either day-month-year or year-month-day but I hate the American month-day-year).

When I go to Manjaro Settings Manager to Add a locale, I have to choose a language and then a “territory”. For language “English” there’s no “Europe” territory. The closest thing is United Kindom, but that gives me a dropdown with “en_GB.UTF8” and “en_GB”, but there’s no “en_150.UTF8”.

For en_150 not sure where it belongs to in Manjaro Settings Manager. Is it different to any other European format which you find with their/your respective country?

However, you can always sudo nano /etc/locale.gen and remove the # in front of en_150.
You’d have to run locale-gen afterwards.

Is it different to any other European format which you find with their/your respective country?

I don’t know, but I don’t want the month and day names in Spanish (or Finnish or Romanian for that matter), I want them in English, but I do want day/month/year, and I want 24 hours as opposed to AM-PM (to me the three things should be three separate options, and the order of month/day/year in numeric format and the 12 vs 24 hours should have nothing to do with place or language, but whatever). Within the choices that KDE presented me, I found that en_150 “English (Europe)” that met those requirements.

Now I see that UK English does the same, so I’ll pick that.

But then there’s measurements. I need metric. In this case British English doesn’t do the trick because it’s imperial.

However, you can always sudo nano /etc/locale.gen and remove the # in front of en_150.

I thought about that, but there’s no en_150 there, commented or otherwise. Can I just add it and it will automagically work?

The AM/PM and 12/24 can also be changed in the clock widget for example without locales and most of the applications also have options to configure different formats, e.g libreoffice calc for metric system. It’s better though to have it maintained at one place than adjusting each application.
For metrics system any European locale offers that.

I personally don’t think you need en_150 at all.
Whether adding it manually works, I think not.

Ok, here’s the workaround that worked for me.

I found out that en_IE.UTF8 (Ireland) actually has both the dates and measurements (metric) that I want.

So in Manjaro Settings Manager I added that, and also es_ES.UTF8 which I need for currency format.

Then went back to KDE Settings and chose en_IE.UTF8 instead of en_150.UTF8 for dates and for measurements (en_ES.UTF8 was already selected for currencies).

I logged out and in, and now the warnings in Perl are gone.

This sounds good now! There’s always more than one way to achieve something :wink: .
