In the above I didn't copy-and-paste the additional info that about 100
packages can be autoremoved after removing libsane1 because after
removing all applications that depend on gtk many libraries are unused.

Title:
  the change from libsane to libsane1 broke many (all?) 3rd party plug-
  ins for sane

Status in sane-backends package in Ubuntu:
  In Progress
Status in sane-backends package in Debian:
  Fix Released

Bug description:
  Impact
  ======
  The Debian maintainer renamed libsane to libsane1 "to match with the soname" 
apparently to fix a Lintian warning.

  libsane 1.0.25 in zesty includes libsane.so.1.25
  libsane1 1.0.27 in artful includes libsane.so.1.27

  This appears to be no bigger change than any ordinary new version of
  the library.

  The library rename makes it impossible to install any scanner drivers
  for libsane that are distributed as a .deb unless the driver
  distributors recompiles against Ubuntu 17.10+.

  Therefore, adding Provides: libsane seems reasonable here.

  Test Case
  =========
  Visit http://support.epson.net/linux/en/iscan_c.html
  Download the amd64 deb .tar.gz
  Unzip it.
  Install the iscan .deb from the core folder.

  It won't install before this SRU because it Depends: libsane

  Regression Potential
  ====================
  The fix here was proposed to the Debian maintainer in July but there's been 
virtually zero response on it.

  It doesn't seem like adding the Provides will make things any worse
  for third-party drivers but it has a good chance of making things
  better for some.

  Original Bug Report
  ===================
  I don't know if that can be prevented in the long run. But both brscan (for 
my brother scanner) and iscan (for my epson scanners) have been broken by the 
change from libsane to libsane1. For iscan I have unpackaged the debian 
package, changed the dependency it contains from libsane to libsane1 and 
installed the changed package. But even then my epson scanners no more work 
leaving me without any scanner => Reporting a bug.
