Try running
sudo apt-get install kmail kdepim-runtime libqt5webengine5 libkf5akonadicontact5 libkf5ksieveui5 libkf5libkdepimakonadi5 libkf5mailcommon5 libkf5messagecomposer5 libkf5messagelist5 libkf5messageviewer5 libkf5pimcommonakonadi5 libkf5templateparser5 libkf5webengineviewer5

It should give some more errors that might explain whats going on here.
