unfortunatly there weren't enough talks submitted for the Debian Day that I have to cancel it until there won't be some new submissions in the next few hours.
So if you want to have a debian day, please submit a talk via the VCC (https://www.linuxtag.org/vcc/). Otherwise it will be canceled.
Update: Mission accomplished. Looks like a few talks were submitted just in time to save the (Debian) day.
