Unfortunately the apt logs are fairly useless. Can you please do this:

  sudo sed -i '1 s/$/x/' /var/lib/dpkg/info/udev.postinst
  sudo apt-get -f install

and then copy&paste the entire output? Thanks!

[Paul Hooijenga (hackedd)]

Unfortunately I don't have the full output from when this was first failing for me, but I eventually worked around it by commenting out the line `addgroup --quiet --system input` in /var/lib/dpkg/info/udev.postinst.

Commenting out the same line also fixed the problem I had today when installing udev 219-7ubuntu6.

[Paul Hooijenga (hackedd)]

Oh, forgot to add, removing the quiet flag from addgroup gives: The group `input' already exists and is not a system group. Exiting.

[Martin Pitt (pitti)]

Ah, thanks. I'm afraid there is not that much that we can do about this then, it's a conflict with a local non-system group. Unless you actually use that, I suggest removing it, and let udev re-create it as a system group.

[Ivo Anjo (knuckles)]

This broke my upgrade from 14.10 to 15.04 :(

I don't know what created the input group, but couldn't this post-install script have a fallback of some kind? I was able to fix it after finding this report, but a normal user would end up with a broken system and a very bad day.

Please consider reopening!

[Ivo Anjo (knuckles)]

I had previously created an input group as per this tutorial:
http://ptichy.blogspot.pt/2014/08/configure-evrouter-on-ubuntu-1404.html?showComment=1434306399108#c1263726685009019900

But I argue that breaking the user's system because of a group name that previously was open for anyone to create (even an "input" user) is scary.

This bug was fixed in the package systemd - 222-1ubuntu1

---------------
systemd (222-1ubuntu1) wily; urgency=medium

  * Merge with Debian unstable. Remaining Ubuntu changes:
    - Hack to support system-image read-only /etc, and modify files in
      /etc/writable/ instead.
    - Keep our much simpler udev maintainer scripts (all platforms must
      support udev, no debconf).
    - initramfs init-top: Drop scsi_wait_scan and udevadm settle, we do that
      in a more sensible way with wait-for-root.
    - initramfs init-bottom: If LVM is installed, settle udev,
      otherwise we get missing LV symlinks. Workaround for LP #1185394.
    - Add debian/udev.lvm2.init: Dummy SysV init script to satisfy insserv
      dependencies to "lvm2" which is handled with udev rules in Ubuntu.
    - Add debian/udev.lvm2.service to avoid running the dummy lvm2 init
      script.
    - Provide shutdown fallback for upstart. (LP: #1370329)
    - debian/extra/ifup@.service: Additionally run for "auto" class. We don't
      really support "allow-hotplug" in Ubuntu at the moment, so we need to
      deal with "auto" devices appearing after "/etc/init.d/networking start"
      already ran. (LP: #1374521) Also run ifup in the background during boot,
      to avoid blocking network.target. (LP: #1425376)
    - ifup@.service: Drop dependency on networking.service (i. e.
      /etc/init.d/networking), and merely ensure that /run/network exists.
      This avoids unnecessary dependencies/waiting during boot and dependency
      cycles if hooks wait for other interfaces to come up (like ifenslave
      with bonding interfaces). (LP: #1414544)
    - Add Get-RTC-is-in-local-time-setting-from-etc-default-rc.patch: In
      Ubuntu we currently keep the setting whether the RTC is in local or UTC
      time in /etc/default/rcS "UTC=yes|no", instead of /etc/adjtime.
      (LP: #1377258)
    - Put session scopes into all cgroup controllers. This makes unprivileged
      user LXC containers work under systemd. (LP: #1346734)
    - systemctl: Don't forward telinit u to upstart. This works around
      upstart's Restart() always reexec'ing /sbin/init on Restart(), even if
      that changes to point to systemd during the upgrade. This avoids running
      systemd during a dist-upgrade. (LP: #1430479)
    - Drop hwdb-update dependency from udev-trigger.service, which got
      introduced in v219-stable. This causes udev and plymouth to start too
      late and isn't really needed in Ubuntu yet as we don't support stateless
      systems yet and handle hwdb.bin updates through dpkg triggers. This can
      be dropped again with initramfs-tools 0.117.
    - Lower Breaks: to plymouth version which has the udev inotify fix in
      Ubuntu.
    - Lower apparmor Breaks: to the Ubuntu version that dropped $remote_fs.
    - Change systemd-sysv's conflicts to upstart-sysv. (LP: #1422681)

    Upgrade fixes, keep until 16.04 LTS release:
    - systemd Conflicts/Replaces/Provides systemd-services.
    - Remove obsolete systemd-logind upstart job.
    - Clean up obsolete /etc/udev/rules.d/README.

  * systemd.postinst: Migrate mountall specific fstab options to standard
    util-linux "nofai...
