Binary package hint: postfix
During a upgrade test from dapper->hardy the following problem occurred:
[71.4563] postfix: Configuring postfix
Postfix was not set up. Start with ^M
cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf^M

/etc/postfix/main.cf (and others) as needed. To view Postfix configuration^M
values, see postconf(1).^M

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.^M

[85.7169] postfix-doc: Configuring postfix-doc
postconf: fatal: open /etc/postfix/main.cf for reading: No such file or directory^M
dpkg: error processing postfix-doc (--configure):^M
subprocess post-installation script returned error exit status 1^M
Debug output of the failed script:
+ set -e
+ [ -x /usr/sbin/postconf ]
+ postconf -e readme_directory=/usr/share/doc/postfix html_directory=/usr/share/doc/postfix/html
postconf: fatal: open /etc/postfix/main.cf for reading: No such file or directory
['/bin/sh', '-ex', '/var/lib/dpkg/info//postfix-doc.postinst', 'configure', '2.2.10-1ubuntu0.1']
This seems to be somewhat difficult to reproduce, but it looks like its dependant on the unpack/configure order that apt is selecting. postfix copies the file in place in the postinst. If both are unapcked and the postinst of postfix-doc is run before the one postfix then this error can happen (that is my current theory :)
