> did restore a recent wily backup though, so these now obsolete udev files in /etc/init & /etc/init.d files might stem from that
Ah, this would explain it then. I just did a dist-upgrade from vivid to current wily, and it works as intended: Setting up udev (225-1ubuntu4) ... Installing new version of config file /etc/init.d/udev ... Installing new version of config file /etc/init/udevmonitor.conf ... addgroup: The group `input' already exists as a system group. Exiting. A chroot environment has been detected, udev not started. update-initramfs: deferring update (trigger activated) Removing obsolete conffile /etc/init.d/udev-finish ... Removing obsolete conffile /etc/init/udev-finish.conf ... Removing obsolete conffile /etc/init/udev-fallback-graphics.conf ... And /etc/init.d/udev-finish is gone. So let's chalk this up as "your backup restored the file". (It's by far *not* a good idea to backup /etc/ in its entirety and restore it! Please just backup files that you actually changed). ** Changed in: systemd (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1498310 Title: /etc/init.d/udev-finish does not get cleaned up on upgrade Status in systemd package in Ubuntu: Invalid Bug description: $ lsb_release -rd Description: Ubuntu Wily Werewolf (development branch) Release: 15.10 $ apt-cache policy udev udev: Installed: 225-1ubuntu4 Candidate: 225-1ubuntu4 Version table: *** 225-1ubuntu4 0 500 http://archive.ubuntu.com/ubuntu/ wily/main amd64 Packages 100 /var/lib/dpkg/status The udev package in wily is missing /lib/udev/udev-finish, hence systemd reports the udev-finish.service as failed.
