hi all,
I've just finished installing knoppix onto my hard drive without any problems . But I want to get clear on some of the things..

1) Is there anything wrongt with the '/etc/apt/sources.list' file, 'cause when I do
Code:
apt-get update
, I get lots of 'file not found' errors and will not be able to install anything. So I edited the sources file to contain only those packages from debian.org. Now, where can I get a list of working mirrors (stable, testing and unstable), so that I can do a nead update.

2) If I have a good sources list file, will
Code:
apt-get update
and
Code:
apt-get upgrade
work properly as in Debian

3) I am not able to install alsa properly. I get the following errors when I try to install alsa

Code:
apt-get -f install
