If one needs old package versions you have a look at snapshot.debian.org [1]. As far as I see you might get away with just installing the two packages [2] and [3] manually. [1] http://snapshot.debian.org/package/kontactinterface/ [2] http://snapshot.debian.org/archive/debian/20180401T155009Z/pool/main/k/kontactinterface/libkf5kontactinterface-data_17.12.3-1_all.deb [3] http://snapshot.debian.org/archive/debian/20180401T155009Z/pool/main/k/kontactinterface/libkf5kontactinterface5_17.12.3-1_amd64.deb (I have not tested it, I am not using that part of KDE.) Kind regards, Bernhard
