I have a minilaptop which shift keys do not work. I want to remap the layout so when I press CapsLock key it behaves like shift. I have seen many turials on this matter but most of them are either too broad or too specific, and I have not been able to solve this problem.
My minilaptop runs Ubuntu 18.04 with the LXDE desktop.
Edit: issue solved!
