If you move files between packages (which appears to be the case here), then you need Breaks + Replaces to avoid that error. In the example given, it would be something like: Breaks: (...) texlive-plain-generic (<< 2020.20200417) Replaces: (...) texlive-plain-generic (<< 2020.20200417) Yes, it is WET but that is sadly the way. Conflicts is *not* sufficient - never has been and never will be. ~Niels
