After upgrading from 16.04 to 18.04 right at the end it gave the following message:

The upgrade has completed but there were errors during the upgrade 
process.

To continue please press [ENTER]

pressed [ENTER]

Now when I do apt update / apt upgrade I get the following message:

The following packages have unmet dependencies:
 systemd : Depends: libsystemd0 (= 229-4ubuntu21.31) but 237-3ubuntu10.48 is installed

Looking in : https://packages.ubuntu.com/bionic/libs/ It shows the following for libsystemd0 for 18.04 anyway. So I'm not sure why the system believes the dependency should be 229-4ubuntu21.31.

libsystemd0 (237-3ubuntu10.38 [amd64, i386], 237-3ubuntu10 [arm64, armhf, ppc64el, s390x]) [security]
    systemd utility library

At the end of apt upgrade it also says:

You might want to run 'apt-get -f install' to correct these.

When I run this I get:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Correcting dependencies... Done
The following packages were automatically installed and are no longer required:
  cgmanager libargon2-0 libcryptsetup12 libgd3 libip4tc0 libjson-c3 libkadm5clnt-mit9 libluajit-5.1-2 libluajit-5.1-common libvpx3 libxpm4 nginx-common
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
  upstart
Suggested packages:
  graphviz upstart-monitor
The following packages will be REMOVED:
  init libpam-systemd systemd systemd-shim systemd-sysv ubuntu-standard
The following NEW packages will be installed:
  upstart
WARNING: The following essential packages will be removed.
This should NOT be done unless you know exactly what you are doing!
  init systemd-sysv (due to init)

Need to get 0 B/392 kB of archives.
After this operation, 18.1 MB disk space will be freed.
You are about to do something potentially harmful.
To continue type in the phrase 'Yes, do as I say!'

Clearly something quite horrible has happened.

I'm a bit out of my depth here and would appreciate some guidance/next steps.

Thanks

You have newer version of libsystemd0 from maybe somewhere. For its downgrade use command below:

sudo apt-get install libsystemd0=229-4ubuntu21.31

and then install upgrades to 16.04 LTS by

sudo apt-get update
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get dist-upgrade # to get newer dependencies

To have a good tool for future possible problems install Aptitude by

sudo apt-get install aptitude

Then reboot and launch system upgrade procedure to 18.04 LTS as usual.
