I am trying to remove yaws-mail package but get errors
 

When i use the synaptic package manager to remove the yaws-mail package it gives an error

and when I use sudo apt-get -f install to try and fix it it gives this error:
E: Sub-process /usr/bin/dpkg returned an error code (1)

I have tried removing it using aptitude and I get the same error.

it seems something is broken but i don't know what.

It is stopping any further installations of packages.

Can anyone shine some light on this problem please.

Thanks

Is that the only error output? If not please post everything that came before that message.
