Why my vsftp service can't start?

Here is my /etc/vsftpd.conf .

listen=on
anonymous_enable=YES
local_enable=YES
write_enable=YES
chroot_local_user=YES
local_root=/home/ftp
anon_root=/home/ftp
xferlog_enable=YES
xferlog_file=/var/log/vsftpd.log

In the console,

service vsftpd start
root@pengsir:/home/debian8# service vsftpd status

When I used sudo /usr/sbin/vsftpd, it gave

500 OOPS: unrecognised variable in config file: allow_ftpd_full_access. 

Once I commented that line, vsftpd started.

first remove the vsftpd packages using these commands.

1 : sudo apt-get remove vsftpd 2 : sudo apt-get remove --auto-remove vsftpd 3 : sudo apt-get purge vsftpd 4 : sudo apt-get purge --auto-remove vsftpd

After This Process Succesfully done.now you can install it again using this command

sudo apt update sudo apt-get install vsftpd service vsftpd status
