Unable to find WWN on Ubuntu 12

Hi All

I am trying to get WWN from the FC adapters to provide to storage admin to provide me with some LUNs, but after some research on google I was asked to use sysfsutils tool, but when I try to install the deb package I got stuck on dependencies.
the one that is giving me issues is : libc6 .
when try to do the following:

dpkg -i libc6_2.15-0ubuntu10.11_i386.deb
(Reading database ... 48300 files and directories currently installed.)
Unpacking libc6:i386 (from libc6_2.15-0ubuntu10.11_i386.deb) ...
De-configuring libc6 ...
dpkg: error processing libc6_2.15-0ubuntu10.11_i386.deb (--install):
 trying to overwrite '/lib/ld-linux.so.2', which is also in package libc6-udeb:i386 2.15-0ubuntu10
Errors were encountered while processing:
 libc6_2.15-0ubuntu10.11_i386.deb

Please can you help in overcoming this
