Ubuntu - VSFTPD configuration for FTP fails on restart

I need to set up a FTP server within my Ubuntu virtual box but I'm having problems within configuration of the config file within VSFTPD From online tutorials I keep seeing different options being selected and different reasoning, I just need a simple and secure configuration without enable settings I do not understand. So far I have selected to use the following options within **/etc/vsftpd.conf**

Listen=NO
Anonymous_enable=NO
Local_enable=YES
wrtite_enable=YES
dirmessage_enable=YES
use_localtime=YES
connect_from_port_20=YES
xferlog_enable=YES
ftpd_banner=Welcome to Toms FTP Server.
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list

From my understanding these options do the following: * listen enables standalone, * anonymous denies non verified login, * write_enable allows to write files, * dirmessage_enable is directory explaining, * use_localtime is the time used for dating files, * connect_from_port_20 is self explanatory, * xferlog_enable is a log creation/format type?, * ftpd_banner is self explanatory, * chroot_local_user specifies users are restricted to their directory, users not restricted to their directory are listed within chroot_list_file. The problem I am having is, I keep seeing references in tutorials regarding a userlist which will state which users do have access like this:

user_sub_token=$USER
local_root=/home/$USER/ftp
userlist_enable=YES
userlist_file=/etc/vsftpd.userlist
userlist_deny=NO

This does not exist in my file and whenever I try to enter it manually it causes my VSFTPD to fail start up when restarting, I see this in almost every tutorial but it is not contained within my configuration files??? Am I trying to configure this wrong? What is the minimum requirements for a safe VSFTPD configuration? Is this user list no-longer supported? Do I even need this user list? error code also does not disappear removing these files and restarting again, it completely breaks the service and requires a re installation every single time, the error code is as follows:

systemctl status vsftpd.service
