Proftpd não pode criar pasta

Question

Deseja: criar pasta e carregar arquivo com www-data: www-data usuário
Tentativa atual: Crie uma pasta, envie um arquivo com ftp: nogroup e filezilla
Resultado: Mesmo com ftp: nogroup pode carregar o arquivo, mas não pode criar pasta
Ação: Tente criar uma nova pasta por ftp
Resultado: permissão negada

Com o Debian 9 e o ACL ativados sem o SELINUX.
Ao instalar WP Hide & Security Enhancer é necessário um serviço de ftp apontando para a instalação do wordpress.

Permissões de pasta:

777 drwxrwxrwx  5 ftp      nogroup  4096 May 30 12:12 /var/www/html
