[Bug 218311] [NEW] upgrade from slapd from dapper to hardy fails on DB conversion

[Martin Emrich]

Public bug reported:

I just tried to upgrade a server with openldap from dapper to hardy (I
pulled an image from the dapper server and am doing a dry-run in a
virtualbox now).

During the upgrade, the slapd postinst script somehow crashed in an
intermediate state, and the upgrade aborted shortly after that.

When I try "dpkg --configure slapd" now, I get this:

root at newsauron:/var/lib/ldap# LANG=C dpkg --configure slapd
Setting up slapd (2.4.7-6ubuntu3) ...
  Backing up /etc/ldap/slapd.conf in /var/backups/slapd-2.2.26-5ubuntu2.6... done.
  Upgrading BDB 'checkpoint' options... .
  Moving old database directories to /var/backups:

  Backup path /var/backups/dc=darkzone-2.2.26-5ubuntu2.6.ldapdb exists. Giving up...
dpkg: error processing slapd (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 slapd


After removing the mentioned backup, I get this:
root at newsauron:/var/lib/ldap# LANG=C dpkg --configure slapd
Setting up slapd (2.4.7-6ubuntu3) ...
  Backing up /etc/ldap/slapd.conf in /var/backups/slapd-2.2.26-5ubuntu2.6... done.
  Upgrading BDB 'checkpoint' options... .
  Moving old database directories to /var/backups:
  - directory dc=darkzone... done.
  Loading from /var/backups/slapd-2.2.26-5ubuntu2.6: 
  - directory dc=darkzone... failed.

Loading the database from the LDIF dump failed with the following
error while running slapadd:
    /var/backups/slapd-2.2.26-5ubuntu2.6/dc=darkzone.ldif: No such file or directory
dpkg: error processing slapd (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 slapd


When I remove both, I get this:
Setting up slapd (2.4.7-6ubuntu3) ...
  Backing up /etc/ldap/slapd.conf in /var/backups/slapd-2.2.26-5ubuntu2.6... done.
  Upgrading BDB 'checkpoint' options... .
  Moving old database directories to /var/backups:

error while running slapadd:

I have pulled an LDIF dump from the (still untouched) original server and rebuilt the database, so my LDAP is up and running again. How can I tell the postinst script that these actions are not necessary?

I have made a snapshot of the VM before starting the upgrade, and I'll
investigate what went wrong after the first upgrade dry-run went
through.

Ciao
