package sysvinit-utils 2.88dsf-41ubuntu6.3 failed to install/upgrade: installing sysvinit-utils would break existing software

This bug was fixed in the package util-linux - 2.27.1-6ubuntu1

---------------
util-linux (2.27.1-6ubuntu1) xenial; urgency=medium

  * Merge from Debian unstable. Remaining changes:
    - Regularly trim SSDs automatically (core-1311-ssd-trimming):
      + Add debian/fstrim-all.cron: Call fstrim --all. Installed as
        /etc/cron.weekly/fstrim.
    - Upstart support:
      + Add hwclock{-save}.upstart, and install them in debian/rules.
      + Drop debian/hwclock.rules and hwclock.default.
    - Add sulogin-fallback-static-sh.patch: Add support for /bin/static-sh as
      fallback if the regular shell fails to execute. Patch ported from
      sysvinit. (see LP #505887)
    - Add sulogin-lockedpwd.patch: Make sure file systems can be fixed on
      machines with locked root accounts (as Ubuntu does by default). Don't
      require --force for sulogin.
    - Make util-linux Breaks old {p,}mac-fdisk for the fdisk binary takeover.
    - Drop debian/util-linux.preinst: Unconditionally deleting files
      is wrong, and dpkg will overwrite symlinks with real files anyway.
    - Drop debian/util-linux.preinst: Unconditionally deleting files
      is wrong, and dpkg will overwrite symlinks with real files anyway.
    - Adjust the Breaks: cloud-utils to 0.27-0ubuntu16 (the Ubuntu version
      that works with util-linux 2.26), and also move it to cloud-guest-utils.
    - Add debian/libblkid1.maintscript to clean up /etc/blkid.conf on upgrade.
      This needs to be kept until after Ubuntu 16.04 LTS.
  * Debian changes fix upgrade failure. (LP: #1556539)

util-linux (2.27.1-6) unstable; urgency=medium

  * Drop (versioned) init-system-helpers dependency to avoid dep loop.
    - initscripts is guaranteed to be installed in stable/jessie, the file
      is additionally a conffile so initscripts will need to be purged to
      cause a problem for us with i-s-h << 1.29 and purging initscripts is
      not possible until after the upgrade anyway. (Closes: #817857)
  * Temporarily move sysvinit-utils back from Breaks to Depends.
    - again seems to confuse apt and we apparently need a synchronized
      upload with sysvinit to move things to how it should (and now can be
      since initscripts dependency was dropped from u-l) be described.

util-linux (2.27.1-5) unstable; urgency=medium

  * Completely drop (versioned) tzdata dependency (Closes: #817371)
    - the alternative on systemd-sysv causes (pre-)dependency loops which
      dpkg can't handle (see example in #817780)
    - the reason for the dependency in the first place seems to have been
      ensuring /etc/localtime is a real file. Later the use of
      /etc/localtime seems to have been removed (see #660365).
      Thanks to Felipe Sateler for digging this information up.
    - tzdata itself is Priority: required so should always be around in a
      regular install even without any dependency on it. (i.e. unless it has
      explicitly been removed.)
