I tried several reboots and several shutdowns all of which succeeded. The issues started on January 20, after the system updates on January 19. I don't know how the Ubuntu startup system (Upstart) works, but my guess is that one of those updates caused the race, and a subsequent update caused the race to disappear. Maybe some of those updates cause upstart service/task dependencies to be recalculated/cached, and this failed on January 19 (causing the unbootable system). A subsequent update may have attempted the same and succeeded, fixing the boot.
Have we eliminated this possibilty so that the resolution to mark this bug report as "Fix Released" is valid? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1412671 Title: [14.04] Boot stuck in "Starting configuring network devices" after upgrade Status in linux package in Ubuntu: Fix Released Bug description: One of these upgrades yesterday resulted in an unbootable system: 2015-01-19 20:32:45 upgrade libc-dev-bin:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:32:47 upgrade libc6-dev:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:32:48 upgrade libc6-dbg:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:32:50 upgrade libc-bin:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:32:53 upgrade libc6:i386 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:32:56 upgrade libc6:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:33:05 upgrade libclutter-gtk-1.0-0:amd64 1.4.4-3ubuntu2 1.4.4-3ubuntu2.2 2015-01-19 20:33:06 upgrade libssh-4:amd64 0.6.1-0ubuntu3 0.6.1-0ubuntu3.1 2015-01-19 20:33:07 upgrade multiarch-support:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5 2015-01-19 20:33:10 upgrade libcgmanager0:i386 0.24-0ubuntu7.1 0.24-0ubuntu7.2 2015-01-19 20:33:11 upgrade libcgmanager0:amd64 0.24-0ubuntu7.1 0.24-0ubuntu7.2 2015-01-19 20:33:12 upgrade linux-firmware:all 1.127.10 1.127.11 I'm unable to debug this any further because the desktop system is in another part of the country. I got the error report by a phone call by a non-technical non-English-speaking user, on whos machine I installed Kubuntu. After a while I got him to boot into the recovery prompt and enable me SSH access so I could downgrade these packages. After downgrading the system restarted well and came up. The user reported that the boot process was stuck at a "Starting configuring network connections" prompt or something. I'm not entirely sure, but I might have heard him muttering something about some cgroup messages. Anyway I still have SSH access, but I can't do on-site debugging until February 7 or restart via SSH and risk having to contact the user to recover from a broken boot.
