package libsane1 1.0.27-1~experimental2ubuntu1: multiarch packages with differing files '/lib/udev/hwdb.d/20-sane.hwdb'

****************
From #3 comment below, to get a workaround, try:

sudo apt-get -o Dpkg::Options::="--force-overwrite" install --reinstall libsane1:i386 (or your real package name)

***************
Has been fixed with:

sane-backends (1.0.27-1~experimental3ubuntu2) bionic; urgency=medium

  * debian/rules: Drop timestamps from conflicting multiarch:same files
    hwdb.d/20-sane.hwdb and rules.d/60-libsane1.rules (closes: #880391)
