package mdk 1.2.6+dfsg-1 failed to install/upgrade: It thought it was already installed, but it was not.

[Removed by request]

I was running muon, installing several packages at once. Muon did not give me sufficient information to ascertain which package was causing the problems.

It may be that more than one package was involved, because I kept getting error messages upon logging into KDE. I tracked some of them down to various speech synthesizing programs that emacs uses.
