I recently reinstalled my Ubuntu 12.04. The main idea was to not disturb files on /home, and I succeeded by reinstalling Ubuntu only on / partition.

When I got back I found everything working but not ubuntu-tweak. I have found many advices such as reinstalling "compiz" or adding older repositories bot none have worked.

When I start ubuntu-tweak in terminal I receive long bundle of code which I don't really understand. I feel it would say important things but I just can not read it properly.

I simply love ubuntu-tweak software and I would like to have it up and running just as before system swap.

There is my problem :

fahrenheit@fahrenheit-1225C:~$ ubuntu-tweak
(ubuntu-tweak:3173): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.

Thank you souravc3, you are THE MAN! It worked! :D It did not exactly helped my case but obviously focused me on matter of language issue. I solved it by updating language manager in system settings and toped English language at the top of the list. Suddenly ubuntu-tweak started to run as it should :) Tank you so much and I would like to thank someone who edited my question so neatly as I would like to post it. I would mark the problem solved but I don't really know how ;P –  user239985 Jan 26 at 15:15

first:

sudo apt-get purge locales

then:

sudo aptitude install locales

and the famous:

sudo dpkg-reconfigure locales

This rids the system of locales, then re-installs locales and downgrades libc6 from 2.19 to 2.13 which is the issue. Then configures locales again.
