Como corrigir um aviso de localidade do Perl?

Ubuntu 22.04LTS

perl -e saída:

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

Tentei remover/limpar locale, reinstalar, locale-gen e também sudo dpkg-reconfigure locales, mas nada mudou. Tenho en_GB.UTF-8, pl_PL.UTF-8, es_ES.UTF-8 instalados.

localectl list-locales retorna:

C.UTF-8
en_GB.UTF-8
es_ES.UTF-8
pl_PL.UTF-8

localidade retorna:

locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_GB.UTF-8
LANGUAGE=en_GB:pl
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC=es_ES.UTF-8
LC_TIME=pl_PL.UTF-8
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY=es_ES.UTF-8
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT=Default.UTF-8
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=

E tenho problema semelhante com Java 17, quando imprimo

System.out.println("file.encoding: " + System.getProperty("file.encoding"));
System.out.println("def charset: " + Charset.defaultCharset() );

a saída é:

file.encoding: ANSI_X3.4-1968
def charset: US-ASCII

Como consertar isso? minha localidade deve ser en_GB.UTF-8
