From 8e37a2bec9b805a677c5c1d60070cbe1d88e5c57 Mon Sep 17 00:00:00 2001 From: "martin f. krafft" Date: Wed, 19 Jun 2013 08:37:14 +0200 Subject: [PATCH 1/3] Fix purging of packages A small error in the reuse of a variable caused packages to never get purged. This commit fixes that.

The only way to identify this state is by looking at the list of installed files of a package. Even if the package has no files installed, this list will be non-empty until the package is removed: # python -c "import apt; c=apt.Cache(); c.update(); c.open(); p=c['ruby1.8']; print p, p.installed, p.installed_files" None [u''] # dpkg --purge ruby1.8 (Reading database ... 27904 files and directories currently installed.) Removing ruby1.8 ... Purging configuration files for ruby1.8 ... # python -c "import apt; c=apt.Cache(); c.update(); c.open(); p=c['ruby1.8']; print p, p.installed, p.installed_files" None [] See http://bugs.debian.org/712749 too. If a package is not marked installed but it still 'has_files', then it should be processed if the request is to purge it.
