Bug#501866: Missing dependancy - libpango1.0-common.prerm uses defoma-app in pkg defoma

Sat Oct 11 02:24:49 UTC 2008

Package: libpango1.0-common
Version: 1.20.5-2
Severity: normal

I dusted off a system that hasn't been upgraded since Oct of 2007.

Upgrading it required a big leap in package versions.  The upgrade
of perl, perl-base, and perl-modules caused several problems.
(I'm filing this report for each package involved, as I'm not sure
where the problem is.)

The following excerpts from my upgrade process (and the dpkg.log
excerpt that follows) show all my apparent dependancy problems.  I
suspect that the half-configure / half-install / unpack step for
perl-modules removed the required modules from the
/usr/share/perl/5.8.8 tree.

The prerm  or postrm scripts for these packages use either
/usr/bin/defoma-app or /usr/sbin/install-docs (in packages defoma and
doc-base).  Those in turn reference files in perl-modules already 
removed, causing libtiff4 to abort the install.  In summary:

   fontconfig.prerm, libpango1.prerm, and libwmf0.2-7.postrm
   all invoke /usr/bin/defoma-app; which needs File/Copy.pm
   from perl-modules.  It was able to continue using the prerm
   script from the new package.

   libpng12-0.prerm, libtiff4.prerm, base-passwd.postinst,
   cupsys.prerm, and shared-mime-info.prerm invoke
   /usr/sbin/install-docs which needs Pod/Usage.pm from perl-modules.

I had a backup of the /usr/share/perl/5.8.8 tree, which I reloaded to
aloow me to complete the upgrade.
