I followed the same path and dist-upgraded all the way to yakkety and saw no errors with the package in proposed. I'm not sure, though, if that really qualifies as a v-d-y, given that I didn't reproduce the original issue in that path.

You may see a file conflict error because a file moved from libsane to libsane-common. This is fairly common, as you can see from the dupes and affect-count. As described in comment #4, only xenial really needs to be patched. But since it shares the same version of sane-backends as yakkety and zesty, it's nice to update both of those so that upgraders get a clean path. [ Test Case ] Install libsane and libsane-common on trusty. Upgrade to xenial. [ Regression Potential ] Tiny. This is just a Breaks/Conflict packaging error. No code changes.
