I ran into this when installing an i386 sane backend on a x64 install

running "sudo apt-get install --reinstall libsane:i386" fixed the issue.

google only finds a bunch of bug reports for "failed to install/upgrade: trying to overwrite shared" but no explanation.

Could be an issue of a missing "Replaces"-declaration somewhere. Possibly related to multiarch, too. https://bugs.launchpad.net/ubuntu/+source/icedtea-web/+bug/1471677/comments/3 strongly suggests this.
