Setting locales on Debian

[Fred White <subscribe@cakafete.com>]

Hello List,

I have to following errors
-bash: warning: setlocale: LC_ALL: cannot change locale (en_GB.utf8)
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

but when I do # locale-gen
-bash: locale-gen: command not found.

Now it seems that I cannot install the locale-gen but locale is install
/# dpkg -l locales
