How to limit a ftp user to only a given subdirectory?

I know this question is posted many times on StackExchange, but none of the solutions worked for me. I use vsftpd server on ubuntu and I want to restrict the access (read-only) for a user to a given subdirectory only. Most of the solutions I found said that changing the home-directory of a user does the job: usermod -d /home/subdirectory with previously setting in /etc/vsftpd.conf: local_enable = YES chroot_local_user=YES chroot_list_enable=YES chroot_list_file=/etc/vsftpd.chroot_list and add the username to /etc/vsftpd.chroot_list. Anyway, this works fine if I use a browser. It directs me to the given home directory and I cannot access its parents. The problem is when I use FileZilla. I connect directly to the home directory but I can also see and access the parent directories (and files within). I also tried some other solutions using sftp with editing the file /etc/ssh/sshd_config and using internal-sftp, but also doesn't work.
