It looks like one of the maintainer scripts for package removal is
failing. One way you can fix this (not very tidy, but it will stop the
errors) is to edit/remove/rename the failing maintainer script.

I think (based on the message above), that this is the file that you
need to edit/remove/rename:

/var/lib/dpkg/info/wx2.8-headers.prerm

And by edit, I mean add something like "exit 0" near the start of the script.
