But I don't have all the folders above:

werner@X10DAi:~$ ~/.emacs.d/auctex
bash: /home/werner/.emacs.d/auctex: No such file or directory
werner@X10DAi:~$ /usr/local/var/auctex
bash: /usr/local/var/auctex: No such file or directory

Yes. See all settings below on my Ubuntu 20.04 box:

(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)
(setq TeX-parse-self t ; parse on load
      TeX-auto-save t  ; parse on save
      ;; use hidden dirs for auctex files
      TeX-auto-local ".auctex-auto"
      TeX-style-local ".auctex-style"
      TeX-source-correlate-mode t
      TeX-source-correlate-method 'synctex
      ;; don't start the emacs server when correlating sources
      TeX-source-correlate-start-server nil
      ;; automatically insert braces after sub/superscript in math mode
      TeX-electric-sub-and-superscript t
      ;; just save, dont ask me before each compilation
      TeX-save-query nil)

I am still not very clear about its working mechanism. Any more hints?
