Public bug reported: This problem occurred while I was using a minimal installation of Ubuntu 12.04 LTS (64-bit), installed from the Minimal ISO and updated as of about 30 minutes before this report was filed. I was using the latest update-manager-core package that is available in 12.04, which I believe is version 1:0.156.14.5 (I no longer have it on my system, as I managed to upgrade before reporting this bug).
What happened: After installing the above version of update-manager- core, setting the "Prompt" variable to "normal" in /etc/update-manager /release-upgrades, and attempting to upgrade to 12.10 (using "sudo do- release-upgrade -d"), the upgrade process unexpectedly crashed with a Python ImportError. The traceback said that it could not locate the module apport.hookutils. I would have expected that apport would have been installed as a dependency of update-manager-core, given that update-manager-core requires that apport modules be present on the system. So, I think that apport needs to be added as a dependency for update-manager-core. Once I manually installed the apport package, the upgrade process worked just fine. ** Affects: update-manager (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport dist-upgrade precise update-manager-core ** Tags added: dist-upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059177 Title: update-manager-core does not list dependency on apport package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1059177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
