There is a dependency missing: libkf5-bin needs to be installed, which did not get pulled in automatically during release upgrade on my system.
Issuing sudo apt-get install libkf5su-bin on the command line fixed the issue. In any case, the file /usr/lib/x86_64-linux-gnu/libexec/kf5/kdesud needs to be in place. Without libkf5su-bin just kdesu is installed in that location.
