Same basic result on precise as well.

Whats puzzling about your result is that update-rc.d is only run in the postinst, which isn't called during remove or purge.

Can you apport-collect on a box you see this on so I can look at the dependencies?

[Adam Gandelman (gandelman-a)]

Sorry clint, the bug actually affects the Openstack Ubuntu Testing PPA. I wish there was a better way to target packages in that PPA and not the Ubuntu package, tho those packages are where the Ubuntu packages are derived.

Anyway, the issue is the use of update-rc.d in the postrm's is bad, and doesn't specify 'remove'. This is fixed in a local branch and will be pushed and upload soon.

This bug was fixed in the package quantum - 2012.2~rc1-0ubuntu1

  [ Adam Gandelman ]
  * debain/*.postrm: Fix argument-less calls to update-rc.d, redirect
    to /dev/null. (LP: #1047560)
  * debian/quantum-server.upstart: Invoke start-stop-daemon properly.
    (LP: #1047404)
  * debain/*.postrm, *.upstart: Ensure files are named for corresponding
    agent package, not plugin package.
  * debian/control:
    - Group agents with plugins.
    - Fix some copy/paste mistakes.
    - Set dependencies between agents and corresponding plugins.
    - Recommend quantum-plugin-openvswitch for quantum-server.
    - Require the same version of quantum-common and python-quantum.
    - Add quantum-netns-cleanup utility to quantum-common.
  * debian/patches/fix-quantum-configuration.patch: Use correct database
    for linuxbridge plugin, use OVS plugin by default, call quantum-rootwrap
    correctly. (LP: #1048668)
  * Fix all use of /usr/sbin, things should go in /usr/bin.
  * Remove dhcp and l3 plugins, they are not actually plugins.
  * Rename packages quantum-plugin-{l3, dhcp}-agent to
    quantum-{l3, dhcp}-agent.
  * debain/quantum-*-agent.upstart: Specify config files as a
    parameter to --config-file, specify log files for all.
  * debian/*.logrotate: Add logrotate configs for server and agents.
  * Install quantum_sudoers with quantum-common, not quantum-server.
  * Install rootwrap filters only with the packages that require them.
  * debian/*-agent.upstart: Specify --config-file=/etc/quantum/quantum.conf
    in addition to plugin-specific config. Specify log files for all agents.
  * Allow group 'adm' read access to /var/log/quantum.
  * debian/quantum-server.postinst: Drop, all has been moved to quantum-common.
  * Add packaging for quantum-plugin-nec.
