CRONTAB-permision danied

Puede editar su crontab de usuario si tiene acceso de superusuario, sin modificar permissions:

 $ sudo crontab -u username -e 

Pensé que usted podría corregir su usuario crontab sin sudo, pero consigo los mismos problemas del permiso que usted, incluso después de crontab grupo de crontab . Los permissions en el crontab de mi usuario ( /var/spool/cron/crontabs ) son -rw------- , el grupo es crontab .
