Saat Instalasi Debian atau Ubuntu, locales mungkin tidak sepenuhnya diinstall. Selama instalasi Perl aplikasi (seperti nagios), peringatan, perl: warning: Setting locale failed, sering muncul.
Pesan peringatan selama instalasi aplikasi Perl akan muncul sebagai berikut:

perl: warning: Please check that your locale settings:
	LANGUAGE = (unset),
	LC_ALL = (unset),
	LANG = "en_US.utf8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Generate di locales

Sering terjadi kesalahan pada locales perl dapat di generated dengan  locale-gen:

Alternativ locale file dapat dibuat manual dengan  localedef :
localedef -i en_US -f UTF-8 en_US.UTF-8

Setting Locale Settings

Locale settings dapat di Set (contoh: en_US.UTF-8) sebagai berikut:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

Perintah Locales dpkgreconfigure akan mengacu untuk Debian untuk memilih locale yang diinginkan.
Opsi ini tidak akan muncul di Distro Ubuntu.
