Create virtual users on Ubuntu 16.06

Hello,

I want to create virtual users that will have dedicated jailed folders(in /var/www/html/users…) with chroot, these users should connect using ftp(vsftpd).

To do this I have followed the steps from approved answer from the link: https://askubuntu.com/questions/575523/how-to-setup-virtual-users-for-vsftpd-with-access-to-a-specific-sub-directory Only difference is that I have left “listen=NO”

Everything seems to be set up okay, only problem is that when I try to connect with ftp, it gives error “500 OOPS: cannot change directory:”.

I have found here how to solve the problem: https://nurikabe.blog/2009/06/15/defeating-vsftp-error-500-oops-cannot-change-directorysomedirectory/ According to this solution I have to run command “getsebool -a | grep ftp”, when I run it I get “getsebool: SELinux is disabled” error. When I run the command “getenforce” it returns “Disabled” despite file in /etc/selinux/config looks like this (SELINUX=enforcing):

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these two values:
# default - equivalent to the old strict and targeted policies
# mls     - Multi-Level Security (for military and educational use)
# src     - Custom policy built from source
SELINUXTYPE=ubuntu

# SETLOCALDEFS= Check local definition changes
SETLOCALDEFS=0

As a bottom line, my problem is that I can’t enable SELinux.

Any ideas what can be the reason of the problem?
