Ooops, probably because it's late. The supposedly duplicate was about the installation of the package and this one about the removal. Sorry.
The cause of the failure is:
====
Removing radvd ...
Stopping radvd: No /usr/sbin/radvd found running; none killed.

Removing tspc ...
Shutting down IPv6 tunnel: invoke-rc.d: initscript tspc, action "stop" failed.
dpkg: error processing tspc (--remove):
subprocess pre-removal script returned error exit status 1
