Ok so I installed ubuntu server on a old HP I managed to acquire. My issue is when I follow some guides online (or even here) I have trouble finding the .conf file(for samba file share) to have already pre-filled content (example going to the global security settings to add or remove lines , etc.) what I usually find is empty files. Even better is sometimes when I confirm that Samba is running and installed and issue the command to kill it to start "editing" the files the terminal returns that the command is not known.
P.S install XFCE UI so I could actually set up the server , FTP, web server and then remove it once done
