One way to answer that is "your `apt dist-upgrade` call": Dist-upgrade sort-of means "give me newer stuff, even if it means sliding sideways and removing some existing parts". You can instead do "apt upgrade" which is more conservative - meaning that it will hold back stuff without a direct upgrade. It is *not* sensible to _only_ do "apt upgrade", you must deal with the pieces leaft behind without a simply upgrade path permitted by conservative upgrading. One way to deal with that is to use aptitude in fullscreen mode to inspect and manually decide what to do with each remaining package (upgrade, remove, hold, downgrade, replace). Another way is to explicitly do "apt install ..." for each package you want to force-upgrade. A nifty trick when using "apt install ..." is that you can remove+avoid packages by negating them: Simply add a hyphen at the end of a package and it won't get installed and if already installed it will get removed.
