[Bug 536958] [NEW] slapd package configuration aborts during Hardy -> Lucid upgrade

[Nathan Stratton Treadway]

Public bug reported:

I am attempting to upgrade my Ubuntu server running Hardy to Lucid,
using "do-release-upgrade -d" from the command line.

After the downloaded "lucid" upgrade script churned away for a while, I
noticed that the slapd package was aborting during the package
configuration.

Here are the applicable lines from the upgrade session:

The do-release-upgrade process continued configuring other packages, but after it completed the "slapd" package is listed as unconfigured; when I tried to configure it manually I got similar errors:

~# dpkg --configure --pending

As it turns out, my do-release-upgrade session was already "planning" to abort due to an non-zero exit status from another package, but I assume this error from the slapd configuration script would also prevent the Hardy -> Lucid upgrade from running to completion.
