Preparando para substituir libc6 2.15-0ubuntu10.3 (usando .../libc6_2.15-0ubuntu10.4_i386.deb) ...

A copy of the C library was found in an unexpected directory:
  '/lib/i386-linux-gnu/libc-2.15.so'
It is not safe to upgrade the C library in this situation;
please remove that copy of the C library or get it out of
'/lib/i386-linux-gnu' and try again.
