Something has been done to be 'helpful' by some entity, and I'd agree the DE is likely to be to blame, if unattended-upgrades has been ruled out. I still find it difficult to believe that someone would recreate the functionality of u-u by other means, but there are a lot of strange people in Linux... A default installation of Debian, without a heavyweight DE, will *not* do this. Not one of the many Debian installations I have ever run has ever resulted in this happening, but then I haven't installed either Gnome or KDE since Gnome 3 arrived. A possible line of approach: you have a list of the recent downloads. It is possible that one of the history.log files under /var/log/apt may be helpful in identifying the time and date of download. The file /etc/crontab and the files under /etc/cron.d contain timed instructions. It may be possible to identify the culprit from time and date correlations. I do use /etc/crontab myself to run simulated upgrades on my servers without downloading anything, but sending an email to me if there are any upgrades available. It will be obvious if you have any cron script that is doing this kind of thing. -- Joe
