* DistUpgrade/DistUpgradeViewNonInteractive.py: - use getWithDefault() for "NonInteractive","ForceOverwrite" (thanks to Free Ekanayaka) * UpdateManager/Core/MyCache.py: - detect dirty dpkg journal and enter recovery mode in this case (thanks to Maco for reporting) * DistUpgrade/DistUpgrade.cfg: - remove kvm-source on upgrade * debian/update-manager-core.links: - use "91-release-upgrade" instead of "91-release_upgrade" to make run-parts happy * fix FTBFS
