Title:
  during dist-upgrade from 16.04 to 18.04, virtuoso-nepomuk blocked
  initscripts from installing

Status in sysvinit package in Ubuntu:
  New

Bug description:
  lsb_release -rd
  Description:	Ubuntu 16.04.6 LTS
  Release:	16.04

  While running distribution upgrade from 14.04 to 16.04, the terminal
  reported too many errors during upgrade and your system may be in an
  unusable state.

  Took a look here:
  https://bugs.launchpad.net/ubuntu/+source/virtuoso-opensource/+bug/1542453

  With fix suggestion:
  I removed /etc/init.d/virtuoso-nepomuk
  then
  sudo dpkg --configure -a
  sudo apt-get purge virtuoso-nepomuk
  sudo apt-get install -f
  sudo apt-get upgrade

  - Found errored packages by running dpkg --configure -a

  - Also took a look at logs in /var/log/dist-upgrade/

  - Searched for related packages of the scripts
  dpkg -S /etc/init.d/virtuoso-nepomuk
  virtuoso-nepomuk: /etc/init.d/virtuoso-nepomuk

  dpkg -S /etc/init.d/binfmt-support
  binfmt-support: /etc/init.d/binfmt-support

  dpkg -S /etc/init.d/screen-cleanup
  screen: /etc/init.d/screen-cleanup

  - Tried to remove errored packages
  apt-get remove virtuoso-nepomuk binfmt-support screen
  ...
  Package 'virtuoso-nepomuk' is not installed, so not removed

  The following packages will be REMOVED:
    binfmt-support playonlinux screen wine wine1.6 wine1.6-i386

  - Tried harder
  apt-get purge virtuoso-nepomuk binfmt-support screen

  The following packages will be REMOVED:
    binfmt-support* screen* virtuoso-nepomuk*

  - Tried to resume upgrade
  apt-get install -f

  this (re-)installed a LOT of packages. Maybe not the best idea.

  - Tried to configure them
  dpkg --configure -a

  Nothing, curious..

  - Tried to resume distribution upgrade
  apt-get dist-upgrade

  The following NEW packages will be installed:
    libfarstream-0.2-5 libpurple0
  The following packages will be upgraded:
    libpurple-bin

  - Autoremoved obsolete packages
  apt-get autoremove

  - Might want to consider reinstalling
  openvpn

  - Doublechecks
  apt-get upgrade
   (nothing)
  dpkg --configure -a
   (nothing)

  apt-cache search wayland
  apt-cache showpkg xwayland
  apt-cache showpkg grub

  - Rebooted, system logged in succesfully. Complained about some crash
  errors, so here is one of them reported.
