Bug#798341: [inkscape] impossible to install inkscape

Hey Mattia,

Thanks a lot for such a detailed answer. It seems that I'm in situation 3b
(it asks me to remove half of the system :( ) as well. I've no idea about
the package that can be generating the issue.

The most problematic package seems to be libsigc++-2.0-0v5 and according to
[1] a complex transition is taking place right now. This can be a potential
cause as well but in this scenario I have no idea about how to proceed.

On the other hand I think that now that I'm better prepared to fix issues
with apt with your recommendations and hints. I really appreciate your help.
