I have also tried removing the erlang and erlang-base packages with apt- get from the command line; it insisted I run apt-get -f install, which is now installing many packages. It's completely unclear what to do if an upgrade fails like this, and most people would not know about apt-get -f install; I am not at all sure that this will actually complete the upgrade successfully.
