Не устанавливается webmin в squeeze

[strike]

Решил поставить webmin на WD My Book Live (это NAS на Debian Squeeze). Остальные пакеты (mc, deluge) поставились нормально, ставил но установка webmin выдает такое:

Removing vsftpd ...
userdel: error deleting shadow password entry
/usr/sbin/deluser: `/usr/sbin/userdel ftp' returned error code 1. Exiting.
dpkg: error processing vsftpd (--remove):

Errors were encountered while processing:
vsftpd
E: Sub-process /usr/bin/dpkg returned an error code (1)

То есть, для установки пакетов нужно удалить vsftpd, но пользователь ftp не удаляется (vsftpd остановлен). Вручную он также не удаляется:

userdel: error deleting shadow password entry
Как это можно исправить?
