You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
  eclipse-gcj: Depends: java-gcj-compat-dev
  java-gcj-compat-headless: Depends: libgcj-common (>= 1:4.4.0-2) but 1:4.3.3-5 is to be installed
  libgcj-bc: Depends: libgcj-common (>= 1:4.4.0-4) but 1:4.3.3-5 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Solution

#dpkg --force-depends --purge java-gcj-compat-dev
#apt-get -f install
