I am really confused and want to share this with you. After updating my system with slapt-get --update and slapt-get --upgrade some of the programs (specially games) don't run anymore. They don't even start.
Games that don't run anymore are: Extreme tux racer, Emilia Pinball, Brutal Chess and FooBillard. They were running perfectly well before the update.
The mirrors I've for slapt-get are:

I can't realize what happened. Maybe some programs, scripts or I don't know what where deleted during the upgrade. I reinstalled the games but they don't run anymore. If any of you can help me or tell me what to do, I will appreciate that.
