package libreoffice-base (not installed) failed to install/upgrade: trying to overwrite '/usr/share/doc/uno-libs3/using-mysql-databases.txt', which is also in package openoffice.org-base 1:3.2.1-7ubuntu2

for now work around it:

  dpkg -r --force-depends openoffice.org-base
  apt-get -f install

This bug was fixed in the package libreoffice - 1:3.3.0~rc4-1ubuntu1
