Investigating (0) udisks [ i386 ] < none -> 1.0.4-3 > ( admin )
Broken udisks:i386 Depends on libdevmapper1.02.1 [ i386 ] < none -> 2:1.02.48-4ubuntu7 > ( libs ) (>= 2:1.02.20)
  Considering libdevmapper1.02.1:i386 3 as a solution to udisks:i386 1
  Holding Back udisks:i386 rather than change libdevmapper1.02.1:i386

Shouldn't have tried to install udisks:i386 on an amd64 system.  This is
a known bug fixed in precise's apt which needs SRUed to oneiric.

** This bug has been marked a duplicate of bug 850264
   given a foreign architecture of i386 on amd64 machine, and an outdated libc, apt tries to remove libc-bin
