Bug#410840: cyrus21-common: purging the package fails (debconf unavailable)

[Bill Allombert]

Package: cyrus21-common
Version: 2.1.18-5
Severity: important

Hello Henrique,

There is an error when attempting to purge cyrus21-common:

  Removing cyrus21-common ...
  Purging configuration files for cyrus21-common ...
  /var/lib/dpkg/info/cyrus21-common.postrm: line 13: /usr/share/debconf/confmodule: No such file or directory
  dpkg: error processing cyrus21-common (--purge):
   subprocess post-removal script returned error exit status 1
  Errors were encountered while processing:
   cyrus21-common

The postrm script cannot rely on debconf to be available when purging.

See Policy 7.2:
  Note, however, that the `postrm' cannot rely on any non-essential packages to
  be present during the `purge' phase.

Cheers,
