I am having issues myself, but I think mine are related to running ubuntu
in a VM on Windows.
I got IT to set aside an unused desktop pc for me to load and run it on
(they say its now on my desk...). Should have results tomorrow or Tuesday.

Title:
Many 3rd party scanner drivers are broken by a sane change
Status in sane-backends package in Ubuntu:
Fix Released

Status in sane-backends package in Debian:

Bug description:
[Impact]
* Starting with Ubuntu 17.10, Ubuntu changed the directory where sane
dll looks for third party drivers. This configuration effectively
broke backward compatibility for all existing third-party drivers.
* A large swath of these third party drivers (most of them) are no
longer supported by the OEM, so maintaining compatibility is
important.
* No open source replacement drivers are currently available, nor
does the community have the resources to easily replace them.
* This bug represents a substantial portion of the scanners in use.

* This was working in the 17.04 release. 18.10 is an LTS release, so
backporting is warranted for the 18.10 release.
[Test Case]
* Following the standard installation procedures for any of the
affected scanner drivers results in the driver files being installed
to /usr/lib/sane/, and sane looking for them in /usr/lib/x86_64-linux-
gnu/sane. When xsane is run, the scanner is not found.
[Regression Potential]
* Regression to previous working sane package often results in the
automatic removal of core system components (documented in the
comments to this bug report), making regression an unusable option for
addressing this bug.
* The available patch is functional and stable in the 19.10 branch.
[Other Info]
* Third party sane drivers in previous version of sane were located under
/usr/lib/sane/, however, the current version of sane on Ubuntu only looks for
64 bit drivers under the /usr/lib/x86_64-linux-gnu/sane directory. /usr/lib64
and /usr/lib64/sane are other directories old drivers are known to install
files to.
* The addition of symlinks alone does not appear to fix this issue,
though it may make the scanner detectable. Changes to udev rules are
also needed to allow proper communications to the scanners. A
selection of workarounds, including working (though not ideal) udev
rules for a number of scanners has been posted to the sane
troubleshooting guide:
