Maybe a release upgrade?

Take a look at

https://serverfault.com/questions/778198/systemd-not-working-after-ubuntu-14-04-to-16-04-upgrade

Before you run the following commands, wait for another reply from the
list, from somebody who verified my hints, to ensure I didn't make a
mistake by accident.

Even if it wasn't a release upgrade, run

  sudo apt clean
  sudo apt update
  sudo apt install --fix-broken
  sudo apt --reinstall install systemd-sysv ubuntu-standard
  sudo apt full-upgrade

if this shouldn't work try running

  sudo apt autoremove
  sudo apt update
  sudo apt install --fix-broken
  sudo apt --reinstall install systemd-sysv ubuntu-standard
  sudo apt full-upgrade

if this shouldn't work, ensure that no third party packages are
installed and no packages are held.

For testing purpose you simply could move away (don't delete it)
your /etc/apt/sources.list and copy the repositories I'm using, to edit
a new /etc/apt/sources.list.

  grep -v "#" /etc/apt/sources.list

Also move away any third party repository, if there should be one
in /etc/apt/sources.list.d/* .

  grep -v "#" /etc/apt/sources.list.d/*

then run

  sudo apt autoremove
  sudo apt update
  sudo apt install --fix-broken
  sudo apt --reinstall --ignore-hold install systemd-sysv ubuntu-standard
  sudo apt full-upgrade

PS: Similar issue, but vice versa, so be careful, respl. consider to make
a full backup, if you want to migrate permanently to upstart:
