I setup a Trusty LXD, installed libsane and libsane-common and then manually updated source.list with the xenial repositories, including xenial-proposed. I then did `sudo apt-get update; sudo apt-get dist- upgrade` and the upgrade completed successfully (no error) with the following versions of libsane and libsane-common.
