problems with locales
 

On debian 8 in a vps

I was getting this below

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

so I purged the locales then rinstalled when i want to reconfiure part of the output is like so

Configuring locales
-------------------

Locales are a framework to switch between multiple languages and allow users to
use their language, country, characters, collation order, etc.

Please choose which locales to generate. UTF-8 locales should be chosen by
default, particularly for new installations. Other character sets may be useful
for backwards compatibility with older systems and software.

--------------------------------------------------
see they maybe so problem with reconfigure or maybe not?

Did you complete the reconfigure step? You make no mention of that.

If so, and still getting the warning, try running:

as root.

Failing that, create /etc/default/locale, and in it, put your locale like such

I think that there is a problem with the in_IN locale in glibc, not Debian specific (Slackware derivative here):This could be causing the issue.

Probably the file /usr/share/i18n/in_IN needs a review.

As a workaround I would tentatively set LANG to en_GB.UTF-8 that should be similar to in_IN.
