Bug Description

do-release-upgrade fails to calculate an upgrade path.
After removing some colliding packages, one last collision remains in /var/log/dist-ugprade/apt.log:

Broken libsensors-config:amd64 collides with libsensors4:amd64 < 1:3.4.0-4 @ii mK >

Trying to remove libsensors4:amd would result in removal of 434 depending packages, including the whole desktop environment.

Is it safe to remove libsensors4 in order to proceed with the upgrade?
