Comment 64 for bug 68053

I had a similar problem, however it was not with Eclipse directly. I simply had a java app that was compiling with gcj against the org.eclipse.swt.gtk.linux.x86_64_3.2.1.v3235.jar.so file.

I followed a similar line of thinking to the above but I downloaded these packages instead:
pool/universe/e/eclipse/libswt3.2-gtk-gcj_3.2.1-0ubuntu2_amd64.deb
pool/universe/e/eclipse/libswt3.2-gtk-java_3.2.1-0ubuntu2_amd64.deb
pool/universe/e/eclipse/libswt3.2-gtk-jni_3.2.1-0ubuntu2_amd64.deb

These files can be found on your nearest mirror. :-)

You can install the packages just by clicking on them, but at some time you're going to have to do a 'sudo apt-get install -f' on a command line to remove the old ones.

This approach protects you from other issues that can happen if you add edgy-proposed to your feed.

I hope this helps someone!

Cheers,
Tudor.
