After installing Ubuntu 18.04 i did enjoying by shared folders, wich i did via File manager Gnome (no terminal and smb.conf editing). But, when, i tryed change chmod and chown on home directory (tryed running web-server as www-data user from homedir, not var/www/html...), my system entryed in logining loop (login via Gnome). After that, i did reset permissions on home dir and logining has earned. But stopped working sharing folders, as manual via smb.conf, as via Gnome sharing. Thinking, in home dir i setted excess or not enough permission...
- to reinstall samba
- manual sharing configuration via smb.conf
