HPLIP installer does not recognize CUPS exists on my Ubuntu 18.04 AMD690G/V system.ystem.

I wonder if the work on bug/1783861 is relevant to my issue. Parts of the
story seem familiar.

Casting about to learn about installing CUPS Required Dependencies. I launched david@david-MS-7367:~$ sudo apt-get install --assume-yes libcups2 cups libcups2-dev cups-bsd cups-client libcupsimage2-dev libdbus-1-dev build-essential ghostscript openssl libjpeg62-dev libsnmp-dev libtool libusb-dev python-imaging policykit-1 policykit-1-gnome python-qt4 python-qt4-dbus python-dbus python-gobject python-dev python-notify python python-reportlab libsane libsane-dev sane-utils xsane
[sudo] password for david:

Note, selecting 'libsane1' instead of 'libsane'
Package python-imaging is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However, the following packages replace it:
  python-pil:i386 python-pil

E: Package 'python-imaging' has no installation candidate
david@david-MS-7367:~$
Now what? Anybody?

Seems to be pointing to Python. But I do not know what I am to do and so am looking for guidance, the following may help?
david@david-MS-7367:~$ sudo apt install python-pil:i386 python-pil

python-pil is already the newest version (5.1.0-1).
python-pil set to manually installed.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help resolve the situation:

The following packages have unmet dependencies:
 python-pil:i386 : Depends: python:i386 (< 2.8) but it is not going to be installed
                   Depends: python:i386 (>= 2.7~) but it is not going to be installed
                   Recommends: python-olefile:i386 but it is not installable
E: Unable to correct problems, you have held broken packages.
