Solution

To fix locales check your language support settings - English (India) should be installed. If not, install it. Then run:

sudo locale-gen en_IN.UTF-8

If that doesn't generate the locale, you can use

sudo dpkg-reconfigure locales

and choose en_IN UTF-8 from the massive list to do the same thing

After generating the locale you want, check the output of locale. You want to see:

LANG=en_IN.UTF-8
LANGUAGE=en_IN:en
LC_CTYPE="en_IN.UTF-8"
LC_NUMERIC=en_IN.UTF-8
LC_TIME=en_IN.UTF-8
LC_COLLATE="en_IN.UTF-8"
LC_MONETARY=en_IN.UTF-8
LC_MESSAGES="en_IN.UTF-8"
LC_PAPER=en_IN.UTF-8
LC_NAME=en_IN.UTF-8
LC_ADDRESS=en_IN.UTF-8
LC_TELEPHONE=en_IN.UTF-8
LC_MEASUREMENT=en_IN.UTF-8
LC_IDENTIFICATION=en_IN.UTF-8
LC_ALL=

If you don't see en_IN.UTF-8 for everything, then do this:

sudo update-locale LANG="en_IN.UTF-8" LANGUAGE=en_IN:en

and check locale again. If the LC variables are still wrong, then do:

nano ~/.pam_environment

and edit so it looks like this:

LANGUAGE=en_IN:en
LANG=en_IN.UTF-8
LC_NUMERIC=en_IN.UTF-8
LC_TIME=en_IN.UTF-8
LC_MONETARY=en_IN.UTF-8
LC_PAPER=en_IN.UTF-8
LC_NAME=en_IN.UTF-8
LC_ADDRESS=en_IN.UTF-8
LC_TELEPHONE=en_IN.UTF-8
LC_MEASUREMENT=en_IN.UTF-8
LC_IDENTIFICATION=en_IN.UTF-8
PAPERSIZE=a4

(leave the papersize alone - I'm not sure what it should be for you!)

Save, exit, type: source ~/.pam_environment and now your locale is fixed.

Problem solved. I removed my own Packages then run these following commands: 'sudo apt-get clean' 'sudo apt-get autoremove' 'sudo apt-get update' 'sudo dpkg --configure -a' 'sudo apt-get install -f' Thanks Zanna.
