электронная почта — & quot; Невозможно открыть основной скрипт: /usr/share/webapps/roundcubemail/webmail/index.php (нет такого файла или каталога) & quot;

Я настроил roundcubemail в соответствии с это archlinux вики используя nginx.

Когда я посещаю /webmail с помощью: https://mail.hackeac.com/webmail страница (в браузере) выдает: «Не указан входной файл», и когда я проверяю логи на /var/log/nginx/roundcubemail_error.log я вижу

2017/12/11 13:44:10 [error] 5827#5827: *1 "/usr/share/webapps/roundcubemailwebmail/index.html" is not found (2: No such file or directory), client: 169.255.184.153, server: mail.hackeac.com, request: "GET /webmail/ HTTP/2.0", host: "mail.hackeac.com"2017/12/11 13:44:19 [error] 5827#5827: *1 "/usr/share/webapps/roundcubemailwebmail/index.html" is not found (2: No such file or directory), client: 169.255.184.153, server: mail.hackeac.com, request: "GET /webmail/ HTTP/2.0", host: "mail.hackeac.com"

Конфигурация Nginx:
