#DEBHELPER#
+# When purging this package after the selections in the preinst have been made,
+# the debconf database is left in an inconsistent state and the package cannot
+# be installed again. This happens because dbconf-common will create a
+# template for these questions with a shared owner. Purging will only delete
+# one of the two templates, leading to a DB state where debconf-set-selections
+# fails. We work around this by manually fixing up the debconf database.
