package slapd 2.4.21-0ubuntu5.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Thank you for taking the time to report this bug and helping to make Ubuntu better.

According to the log files:

Setting up slapd (2.4.21-0ubuntu5.2) ...
  Backing up /etc/ldap/slapd.d/ in /var/backups/slapd-2.4.21-0ubuntu5... done.
Starting OpenLDAP: slapd - failed.
The operation failed but no output was produced. For hints on what went
wrong please refer to the system's logfiles (e.g. /var/log/syslog) or
try running the daemon in Debug mode like via "slapd -d 16383" (warning:
this will create copious output).

Below, you can find the command line options used by this script to
run slapd. Do not forget to specify those options if you
want to look to debugging output:
  slapd -h 'ldap:/// ldapi:///' -g openldap -u openldap -F /etc/ldap/slapd.d/
invoke-rc.d: initscript slapd, action "start" failed.

Could you look at and attach /var/log/syslog to help figuring out why slapd failed to restart?

Mathias,
Glad to do what I can to help but bear in mind I'm no Linux expert :)
That said, this seems to be the relevant part of syslog:

What's the history of this system? Was this system running jaunty at
some point then upgraded to karmic and then lucid?

Could you attach the following file to the bug?

/etc/ldap/slapd.d/cn=config/olcDatabase={-1}frontend.ldif

Mathias,
Yes, this file has been upgraded through several iterations of Ubuntu, not sure which one I started at.
Requested file attached.
John

That should have read "this computer" not "this file".
