Hi
I had the Same bug...

 I was connected with root user (allowroot=true in gdm.conf),
upgrade launched with a : # nohup update-manager -d &

After automatic dpkg at the post installation and a reboot, then  ...
all upgrade  is ok !

I just noticed that in /etc/gdm file gdm.conf was renamed to gdm.conf.dpkg-bak 
(and -old)
gdm now works without gdm.conf  (///=> custom.conf)

-- 
package gdm 2.28.0-0ubuntu8 failed to install/upgrade: subprocess installed 
post-installation script returned error exit status 1
