I just noticed that the wheezy archives have been removed. This breaks pygame for touchscreens, because the version of libsdl1 of Raspbian is broken since Jessie. To make pygame work with tslib you need to downgrade to the wheezy version.
For details on this issue see https://learn.adafruit.com/adafruit-2-4 ... ygame-tips. Adafruit also supplies a downgrade-script which does not work anymore.
So please, please restore the wheezy archives. Or, if anybody knows an alternative url to http://archive.raspbian.org/raspbian with wheezy packages, please let me know.
