df returning negative file sizes and apt-get not very happy

[Pritpal Dhaliwal <pdhaliwal@bluelithium.com>]

so today I was trying to install testing mysql-server and I think I 
messed couple of things up..

here is what df returns:

bigmonster:~# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda2            -3159243779106k  1.0k  0.0k   7% /
bigmonster:~#


Here is what apt-cache policy libc6 return:
bigmonster:~# apt-cache policy libc6
libc6:
  Installed: 2.3.2.ds1-16
  Candidate: 2.3.2.ds1-16
  Version Table:
 *** 2.3.2.ds1-16 0
        100 /var/lib/dpkg/status
     2.2.5-11.5 0
        500 ftp://ftp.us.debian.org stable/main Packages

        500 ftp://linux.csua.berkeley.edu stable/main Packages

and here is what I get when I try to install locales:
Sorry, but the following packages have unmet dependencies:
  locales: Depends: glibc-2.2.5-11.5
E: Sorry, broken packages

I need locales for mysql-server I believe.

but I think what I have successfully done is.. confused apt-get big time 
and now apt-get is not so happy with me.

can anyone help me to get my df back to normal?  and apt-get too. .

thanks a lot in advance..
