OK. So you have everything set correctly.

I'm not sure what you mean by your question. Do you mean that you've
installed 11.10, 12.04, 12.10, and 13.04 and had this error with all
of them?

I've had these locale errors once in the past and I just recompiled my
chosen locale with "locale-gen" to get rid of this error.

I've just tried the following in a VM (I used "--purge" to get clean
output, if you do this you'll lose your Telegu locales):

# locale-gen --purge en_US.UTF-8 en_IN
Generating locales...
  en_IN.UTF-8... done
  en_US.UTF-8... done
Generation complete.

# localedef --list-archive
en_IN
en_IN.utf8
en_US.utf8

The "locale-gen" command failed when specifying "en_IN.utf8" or
"en_IN.ISO8859-1". I have no idea why; especially for "en_IN.UTF-8"
since it's generated when using "en_IN" and it's listed in
"/usr/share/i18n/SUPPORTED". (Furthermore, I have no idea why you have
the message about "en_IN.ISO8859-1"!)

Maybe setting "en_IN.UTF-8" for LANG in "/etc/default/locale" will fix
your problem without having to recompile locales; but I doubt it.
