你好，我在 Ubuntu Server 20.04.1 LTS 中创建了一个 vsftpd 服务器，但出现了错误，这是我的配置文件，错误信息以及我创建 SSL 密钥的人员。（抱歉我的英语太差了）
我的 vsftpd.conf 档案

chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list
userlist_enable=YES
userlist_file=/etc/vsftpd.userlist

systemctl status 中的错误
The error in systemctl status

我创建密钥的命令
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/vsftpd.pem -out /etc/ssl/private/vsftpd.pem
