Thanks for this additional information and the correction. I updated the title+description accordingly. So to summarize:
Postinst failure from gnat-gps-doc: Setting up gnat-gps-doc (3.1.3-2ubuntu1) ... No `START-INFO-DIR-ENTRY' and no `This file documents'. install-info(/usr/share/info/tutorial.info): unable to determine description for `dir' entry - giving up dpkg: error processing gnat-gps-doc (--configure): subprocess post-installation script returned error exit status 1 Postinst failure from nfs-kernel-server: Setting up nfs-kernel-server (1.0.9-2ubuntu1) ... Installing new version of config file /etc/init.d/nfs-kernel-server ... dpkg: error processing nfs-kernel-server (--configure): subprocess post-installation script returned error exit status 1 Problem with the conffile prompt of nfs-kernel-server (that sounds like it might be a duplicate of #69051 ?).
