I would like to ask you in advance sorry for my English ... try for the best ...

I studied physics at the University of Crete and there I did my Master. https://docs.google.com/open?id=0BxaG1GVbo3S5UVFhNjRURXJ1eHc

The LaTeX then seemed too hard and so did not bother to put at my priorities until I tried to write my first notes for my courses... I realized then that the word and openoffice doesn't help my to write quality documents.

With Latex deal from 2010 in my attempt to write notes for my students and has since stuck

The OS that I use is Ubuntu 20.04

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.
