It's trying to symlink the configuration files into the data directory
before calling pg_upgrade. I think it complains that the symlinks are
already there, from a previous runs. Could could try manually removing
them from the data directory.

This was apparently fixed in postgresql-common version 155 (see
https://github.com/petere/postgresql-common/commit/323253ed95ec00faaf042217749e3f4c7e3617b3)
If you want to, you could also try to get an updated version from
apt.postgresql.org.
