Frankly, I’m tempted to reassign this to dpkg; Policy §7.2 is very clear on the relationship between prerm scripts and Depends. It’s not the first time I’ve seen this, although it usually happens when there is a dependency cycle: one of the dependencies of a package in the Depends list can be in a broken state at the time of prerm running. Dpkg needs to ensure that all dependencies *and their own dependencies* are in a clean, installed state when running the prerm script. It correctly does it for postinst already. > -----Original Message----- > From: Josselin Mouette [mailto:[EMAIL PROTECTED] > Sent: Monday, October 13, 2008 04:36 > To: Higgins, Paul; [EMAIL PROTECTED] > Subject: Re: Bug#501866: Missing dependancy - libpango1.0-common.prerm uses > defoma-app in pkg defoma > > Le vendredi 10 octobre 2008 à 22:24 -0400, Paul Higgins a écrit : > > 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).
