Reproducer: sudo apt-get install --reinstall python3 The actual bug is that apport ships a file /usr/share/python3/runtime.d/apport.rtupdate . This is not supposed to be there (autogenerated by dh_python3, I assume), and is just plain wrong. I'll remove it.
This will leave the remaining tasks open, but will stop breaking upgrades and thus be a lot less urgent. ** Also affects: apport (Ubuntu) Importance: Undecided Status: New ** Changed in: apport (Ubuntu Quantal) Importance: Undecided => Critical ** Changed in: apport (Ubuntu Quantal) Status: New => In Progress ** Changed in: apport (Ubuntu Quantal) Milestone: None => quantal-alpha-2 ** Changed in: apport (Ubuntu Quantal) Assignee: (unassigned) => Martin Pitt (pitti) ** Changed in: apport-symptoms (Ubuntu Quantal) Importance: Critical => Medium ** Changed in: apport-symptoms (Ubuntu Quantal) Status: Confirmed => In Progress ** Changed in: apport-symptoms (Ubuntu Quantal) Assignee: (unassigned) => Martin Pitt (pitti) ** Changed in: dkms (Ubuntu Quantal) Importance: Critical => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1013171 Title: Many package hooks not ported to python3 Status in “apport” package in Ubuntu: In Progress Status in “apport-symptoms” package in Ubuntu: In Progress Status in “bluez” package in Ubuntu: New Status in “dkms” package in Ubuntu: Confirmed Status in “firefox” package in Ubuntu: Confirmed Status in “gnome-screensaver” package in Ubuntu: Confirmed Status in “libatasmart” package in Ubuntu: Confirmed Status in “mdadm” package in Ubuntu: Confirmed Status in “network-manager” package in Ubuntu: Confirmed Status in “notify-osd” package in Ubuntu: Confirmed Status in “shadow” package in Ubuntu: Confirmed Status in “thunderbird” package in Ubuntu: Confirmed Status in “udisks2” package in Ubuntu: Fix Committed Status in “xdiagnose” package in Ubuntu: In Progress Status in “apport” source package in Quantal: In Progress Status in “apport-symptoms” source package in Quantal: In Progress Status in “bluez” source package in Quantal: New Status in “dkms” source package in Quantal: Confirmed Status in “firefox” source package in Quantal: Confirmed Status in “gnome-screensaver” source package in Quantal: Confirmed Status in “libatasmart” source package in Quantal: Confirmed Status in “mdadm” source package in Quantal: Confirmed Status in “network-manager” source package in Quantal: Confirmed Status in “notify-osd” source package in Quantal: Confirmed Status in “shadow” source package in Quantal: Confirmed Status in “thunderbird” source package in Quantal: Confirmed Status in “udisks2” source package in Quantal: Fix Committed Status in “xdiagnose” source package in Quantal: In Progress Bug description: While trying to upgrade from 12.04 to Quantal I received an error of: Could not install python3: subprocess installed post-installation script returned error exit status 4 ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: python3 3.2.3-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-23.36-generic 3.2.14 Uname: Linux 3.2.0-23-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.2.2-0ubuntu2 Architecture: amd64 Date: Thu Jun 14 09:13:21 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) PackageArchitecture: all ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: python3-defaults UpgradeStatus: Upgraded to quantal on 2012-06-14 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1013171/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
