Answer 1

Looks like the UTF-8 locale en_IN has not been generated on your system. So then generate it:

sudo locale-gen en_IN

Edit:

The error messages reveal a bug in Software Updater. A workaround to get rid of the error messages is to change LANG to "en_IN.UTF-8".

sudo update-locale LANG=en_IN.UTF-8

Edit II:

To fix the new problem, try these commands:

sudo rm -f /var/lib/apt/lists/*
sudo apt-get update

Answer 2

Change /etc/default/locale settings to en_IT.UTF-8:

LANG="en_IT.UTF-8"
LC_NUMERIC="en_IT.UTF-8"
LC_TIME="en_IT.UTF-8"
LC_MONETARY="en_IT.UTF-8"
LC_PAPER="en_IT.UTF-8"
LC_NAME="en_IT.UTF-8"
LC_ADDRESS="en_IT.UTF-8"
LC_TELEPHONE="en_IT.UTF-8"
LC_MEASUREMENT="en_IT.UTF-8"
LC_IDENTIFICATION="en_IT.UTF-8"
LANGUAGE="en_IT:en"
