What i did to start upgrade:
-deleted sources.list.save
-deleted sources.list.distUpgrade
-renamed sources.list.d to sources.list.disabled
-created empty sources.list.d
-started upgrade LANG=en_US.UTF8 sudo do-release-upgrade -d

I don't know which step is really mandatory but it seems that .list files parser crashes upgrader, so it is better to leave a single minimal sources.list file for upgrade procedure and then return and update all custom .list files manually after upgrade.
