I have an install of Mathematica 11.2 that worked without problems until now, but now, after not using it for a few months, it does not start up (hanging on "Initialising kernels...").
I tried to start
wolfram from the terminal, which immediately give a seg fault.
I also renamed the mathematica folders as described here here, but the only effect that had was that it hung on "Initialising preferences... " instead.
I am running Kubuntu 17.10.
I am not sure what I can try next, so any ideas would be appreciated.
