Hiya. Only 2 months new to Knoppix and rather unconfident in general but I'm slowly learning. It all started when I was trying to install mplayer so I can watch streaming wmv stuff. A guy on another board said I need mplayer and alsa so I set about getting them but it didn't work. I tried using apt-get and by manually downloading .deb files and all sorts of stuff which I probably should have learnt up on a bit before attempting Now when I run "apt-get -f install" (which has helped me in the past) I get:

Code:
# apt-get -f install

Basically I am not interested enough to keep trying to install mplayer or any alsa stuff which isn't needed, I can live without it and the general learning curve of Linux is such that I'd rather concentrate on more important issues but I'd suspect the above is not exactly a desirable way to have my system. By all means if you can suggest things to try out, please do, but I'm also wondering what the general course of action that I'm supposed to take is? Should I be trying to uninstall knx-alsa or am I completely off-track? And that Broken Pipe thing doesn't sound too promising. If you suggest any codes, it would be fantastic if you could tell me what they're actually doing, but I'm not fussy. Oh well, thanks for any help.
