Solucionar: Can’t set locale; make sure $LC_* and $LANG are correct

Me encuentro aveces con el siguiente error en un Linux (lo dejo acá como ayuda de memoria y si alguien le pueda ayudar)

Can't set locale; make sure $LC_* and $LANG are correct!
 perl: warning: Setting locale failed.
 perl: warning: Please check that your locale settings:
 LANGUAGE = (unset),
 LC_ALL = (unset),
 LC_CTYPE = "en_US.UTF-8",
 LANG = "en_US.UTF-8"
 are supported and installed on your system.
 perl: warning: Falling back to the standard locale ("C").
 locale: Cannot set LC_CTYPE to default locale: No such file or directory
 locale: Cannot set LC_MESSAGES to default locale: No such file or directory
 locale: Cannot set LC_ALL to default locale: No such file or directory

Para solucionar esto, se ejecuta

dpkg-reconfigure locales

(en Debian y derivados)

Seleccionas el locale -en este caso en_US.UTF-8- y con eso se soluciona.
