Removing xfonts-traditional would break your X server by removing "fixed".

You should not remove xfonts-traditional while "fixed" refers to one
of its fonts.  You probably want to check the differences between the
various /etc/X11/fonts/misc/xfonts-base.alias*, reconcile any changes,
and then run "update-fonts-alias misc".  After that you can retry the
removal.
