Hello. I'm using Mepis and was trying to install the nVidia drivers using the instructions found here:
http://home.comcast.net/~andrex/Debi...tallation.html

During step 2 (Install the nVidia user-space libraries) when i'm trying to install nvidia-glx (apt-get -t unstable install nvidia-glx), i run into the error below. One of the depdancies is tzdata, which is failing to install. I've tried installing tzdata various different ways, including -f, and i always get this error. Can anyone help?

Code:
