Package: nut-server Version: 2.8.0-7 Severity: critical Justification: communication with ups fail
Dear maintainer, Here goes the description of a critical bug in the driver for the Riello UPS SPW 5000 A3 (riello_usb), perhaps affecting other Riello UPS models.

Seems the bug exists in the riello_usb driver, not in the whole package or debian version. -- Daniele Nuzzo
