I smell Multi-Arch:same version-screw. The way we tell the resolver to not travel down this road is by reseting the candidate version – but that means it has no chance to know later on that that package was "upgradeable"… The usual resolver debug flags could be interesting: -o Debug::pkgDepCache::Marker=1 -o Debug::pkgProblemResolver=1 Please also save your /var/lib/dpkg/status and /var/lib/apt/lists/ somewhere as resolver things are highly state dependent and disappear usually within a few mirror updates. And as you have a new enough apt version, lets run apt with -o Dir::Log::solver=/tmp/edsp.log.xz also as that should collect all relevant information of system state for the resolver in one still big but at least highly compressed file I might want to have later if my guess from above is completely wrong.
