This does not necessarily look like gdm3's fault to me.

There does seem to be a bug of some sort here: gdm3.postinst shouldn't
exit unsuccessfully without a message. If you edit
/var/lib/dpkg/gdm3.postinst and add a line "set -x" just below the "set
-e", then retry the installation, it might become clearer what went wrong?

Where does this /etc/init.d/vpnagentd_init script come from? I think
this is what's causing the problem.

It looks as though that script needs LSB tags
(<http://wiki.debian.org/LSBInitScripts>) in order for the installation
of any package with an init script to succeed.

As a result, laptop-mode-tools, gdm3 and exim4-base (which each contain
an init script) all fail to install:
