I am currently dealing with a “package is in a very bad inconsistent state - you should reinstall it before attempting configuration.” problem. It is due to a faulty installation of wolfram-engine.
As far as I know, PiPlay is meant to be a distribution that focuses on emulation :) Is the Wolfram Engine really necessary? The install package takes up close to 500 MB (not counting any possible dependencies) and it seems dumb to bloat a distribution meant to be run on perhaps small 4 GB sd cards.
Is Wolfram Alpha just something leftover from the Raspbian distro?
