Hi, enabling checksumming seems to work around the problem reported here.
After activating checksumming, i got some of these messages in var/log/apt-cacher/error.log: | Fri Apr 18 23:25:39 2008|10.2.1.3| ALARM! Faulty package in local cache detected! Removing, to be replaced with the next download. apt-cacher then re-downloads the affected files and successfully serves them. - Dietrich -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
