I was trying to install Moonlight, but following the commands didn't work.
Now I don't care about that any more, but my Software Center and Update Center kept on crashing. I managed to get rid of them through the terminal, but reinstalling them is proving to be a problem I keep on running into.
Output from the terminal, which is as I think a piece of information left over from the attempt to install
E: Type 'echo' is not known on line 2 in source list /etc/apt/sources.list.d/mono-xamarin.list E: The list of sources could not be read.
How to I get rid of this and reinstall my Software/Update Center?
