vsftpd won't start: "systemd[1]: vsftpd.service: main process exited, code=exited, status=2/INVALIDARGUMENT"

I have Rapsberry Pi B+ with Arch Linux installation. uname reports version: [computer@computer001 ~]$ uname -a Linux computer001 3.18.3-3-ARCH #1 PREEMPT Mon Jan 26 20:10:28 MST 2015 armv6l GNU/Linux I've installed ftp server via pacman -S vsftpd and installation has passed without any errors. Then I tried to configure it, which resulted in following vsftpd.conf: anonymous_enable=NO local_enable=YES write_enable=YES #local_umask=022 anon_upload_enable=NO anon_mkdir_write_enable=NO dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES chown_uploads=YES chown_username=computer #xferlog_file=/var/log/vsftpd.log #xferlog_std_format=YES #idle_session_timeout=600 #data_connection_timeout=120 #nopriv_user=ftpsecure #async_abor_enable=YES #ascii_upload_enable=YES #ascii_download_enable=YES ftpd_banner=Welcome to personal ftp service. #deny_email_enable=YES #banned_email_file=/etc/vsftpd.banned_emails #chroot_local_user=YES #chroot_list_enable=YES #chroot_list_file=/etc/vsftpd.chroot_list ls_recurse_enable=YES listen=YES #listen_ipv6=YES Now, when I try to restart vsftpd, I get: [computer@computer001 etc]$ sudo systemctl restart vsftpd.service && systemctl status -l vsftpd.service * vsftpd.service - vsftpd daemon Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Thu 1970-01-01 06:32:24 UTC; 112ms ago Process: 350 ExecStart=/usr/bin/vsftpd (code=exited, status=2) Main PID: 350 (code=exited, status=2) Here is also output of sudo journalctl | grep -i vsftp: Jan 01 06:32:24 computer001001 sudo: computer001 : TTY=pts/0 ; PWD=/etc ; USER=root ; COMMAND=/usr/bin/systemctl restart vsftpd.service Jan 01 06:32:24 computer001001 systemd: Starting vsftpd daemon...

I am also aware date/time is not correct, I haven't setup it yet.What am I missing?
