Problems that can arise if user moves matter folder, or deletes it

Thanks for catching this! I think it should be fixed now.

I opened a new issue (#68) for discussing ways of improving the installation process. I will close this one as this particular problem with apt remove should be patched for now. Feel free to re-open it if you see fit.
