The entire error is a red herring, I now think. A cron job was running that started an "apt-get upgrade" while the dist- upgrade was running. Ouch.
Edited the <package>.postinst file that subsequently crashed, stopped cron, did a dist-upgrade, then removed and reinstalled the package in question. Everything works fine. This is the first distribution in years that handles suspend/resume robustly on my laptop - many thanks to whoever fixed the kernel. Perhaps do-release-upgrade should suspend cron processing while upgrading? If that is the intention, then it didn't work. I will add the files if you still think it useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070684 Title: Fatal error during do-dist-upgrade 12.04 -> 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1070684/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
