package fglrx-updates not installed failed to install/upgrade: Unterprozess neues pre-installation-Skript gab den Fehlerwert 1 zurück

[lptr]

I previously installed this proprietary driver from ATI
amd-driver-installer-8.982-x86.x86_64.run

after yesterdays update I recognized that no 3D functionality was given. So I tried to activate the default drivers provided in systemsettings hardware. This resulted in this failure.

Currently I am in the position that I need to uninstall ATI drivers and reinstalling them again.
