SSH locale

Same problem on my Ultra 4, RAIDiator 4.2.19.

dpkg -L libc6 says that it should include /usr/bin/localedef, but the file just isn't there, and I'm not sure of any way to reinstall libc6.

I reinstalled RAIDiator a while back after trying to fix this problem and making it worse, so I'm hesitant to fiddle too much...

Would really love to find a way to sort out this annoyance if anyone can offer advice...?

Some possibly relevant extra info about my system...

binaries in /bin, /sbin, /usr/bin, /usr/sbin, /usr/local/bin, /usr/local/sbin matching 'locale*'

/usr/bin/locale*
/usr/sbin/locale-gen*

Relevant looking environment variables:

LANG=en_AU.UTF-8
LC_CTYPE=en_AU.UTF-8

Locale -a output:

% locale -a
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_COLLATE to default locale: No such file or directory
C
POSIX

in the /usr/share/locale directory:

af/  ca/  da/     de_DE/  en_GB/  es_ES/  fi/     gl/  hu/     it/  ko/  nl/  pl/     pt_PT/  sk/  sv/  tr/  zh_CN/
bg/  cs/  de/     dz/     eo/     es_PE/  fr/     he/  hu_HU/  ja/  nb/  nn/  pt/     ro/     sl/  te/  uk/  zh_TW/
bs/  cy/  de_CH/  el/     es/     eu/     fr_FR/  hr/  id/     km/  ne/  pa/  pt_BR/  ru/     sq/  tl/  vi/

Oddly there is no en_US or en_AU, let alone 'en_XX.UTF-8' directories. The only "en*" directory here is "en_GB".
