Upgraded to 12.10, can't install Eclipse

[Oliver Ruebenacker]

     Hello,

  I just upgraded from 12.04 to 12.10. Before the upgrade, I had
Eclipse installed, but it disappeared. I went to the Ubuntu Software
Center and tried to install Eclipse from there, but it complains about
unresolved dependencies:

The following packages have unmet dependencies:

eclipse-platform: Depends: eclipse-platform-data (>=
3.8.0~rc4-1ubuntu1) but 3.8.0~rc4-1ubuntu1 is to be installed
                  Depends: eclipse-rcp (= 3.8.0~rc4-1ubuntu1) but
3.8.0~rc4-1ubuntu1 is to be installed
                  Depends: liblucene2-java (< 2.9.5) but 2.9.4+ds1-4
is to be installed
                  Depends: sat4j (< 2.4.0) but 2.3.1-1ubuntu1 is to be installed

  I don't even understand what some of the errors mean: e.g.: isn't
the required version of eclipe-platform-data exactly the one to be
installed?

  Any ideas? Thanks!

     Take care
     Oliver
