After a system upgrade, when I attempt to use LaTeX, I get the following error from within my compiler (TexMaker). I have no idea what it means. What should I do? (I did not set up TeX on the computer in the first place and don't know how to do that; I know how to open the terminal and do a few simple things but other than that am in over my head.)
