[Observium] tar: Error is not recoverable: exiting now

Hi guys,

I'm trying to install Observium OSE but when I try to untar, I got an error.

I downloaded this file : http://www.observium.org/observium-community-latest.tar.gz

observium/includes/discovery/humidity/apc.inc.php tar: Fin prématurée rencontrée dans l'archive. tar: Fin prématurée rencontrée dans l'archive. tar: Error is not recoverable: exiting now

Thanks in advance

Maxence
