Comment 30 for bug 1571640

AIUI unity-greeter 16.04.3 should fix this issue now, but it was rejected because at the time the fix to u-s-d wasn't available in xenial. There's an additional issue that the dependency on u-s-d was updated to require a fixed version of u-s-d, but that was done incorrectly and so the control file is kinda broken. If I'm wrong about any of this, please correct me.

I'm willing to do some work here, but I don't know what's the right thing (i.e., will get merged and released) to do. Fix the dependency in debian/control to >= 15.04.1+16.04.20160701-0ubuntu1?
